<td>: The Table Data Cell element - HTML: Hypertext Markup Language
headers this attribute contains a list of space-separated strings, each corresponding to the id attribute of the <th> elements that apply to this element.
...each string is the id of a group of cells that this header applies to.
... scope this enumerated attribute defines the cells that the header (defined in the <th>) element relates to.
... only use this attribute with the <th> element to define the row or column for which it is a header.

Basics of HTTP - HTTP
on top of these basic concepts, numerous extensions have been developed over the years that add updated functionality and semantics with new http methods or headers.
... separating identity and location of a resource: the alt-svc http header most of the time the identity and location of a web resource are shared, this can be changed with the alt-svc header.
...this article explains how this is accomplished using the content-type header and the mime standard.
... content negotiation http introduces a set of headers, starting with accept as a way for a browser to announce the format, language, or encoding it prefers.

Accept-Ranges - HTTP
the accept-ranges response http header is a marker used by the server to advertise its support of partial requests.
... in presence of an accept-ranges header, the browser may try to resume an interrupted download, rather than to start it from the start again.
... header type response header forbidden header name no syntax accept-ranges: <range-unit> accept-ranges: none directives <range-unit> defines the range unit the server supports.
... none no range unit is supported, this makes the header equivalent of its own absence and is therefore rarely used, though some browsers, like ie9, it is used to disable or remove the pause buttons in the download manager.

Accept - HTTP
the accept request http header advertises which content types, expressed as mime types, the client is able to understand.
... using content negotiation, the server then selects one of the proposals, uses it and informs the client of its choice with the content-type response header.
... browsers set adequate values for this header depending on the context where the request is done: when fetching a css stylesheet a different value is set for the request than when fetching an image, video or a script.
... header type request header forbidden header name no cors-safelisted request header yes, with the additional restriction that values can't contain a cors-unsafe request header byte: 0x00-0x1f (except 0x09 (ht)), "():<>?@[\]{}, and 0x7f (del).

Age - HTTP
the age header contains the time in seconds the object has been in a proxy cache.
... the age header is usually close to zero.
... if it is age: 0, it was probably just fetched from the origin server; otherwise it is usually calculated as a difference between the proxy's current date and the date general header included in the http response.
... header type response header forbidden header name no syntax age: <delta-seconds> directives <delta-seconds> a non-negative integer, representing time in seconds the object has been in a proxy cache.

Allow - HTTP
the allow header lists the set of methods supported by a resource.
... this header must be sent if the server responds with a 405 method not allowed status code to indicate which request methods can be used.
... an empty allow header indicates that the resource allows no request methods, which might occur temporarily for a given resource, for example.
... header type entity header forbidden header name no syntax allow: <http-methods> directives <http-methods> the comma-separated list of allowed http request methods.

Clear-Site-Data - HTTP
the clear-site-data header clears browsing data (cookies, storage, cache) associated with the requesting website.
... header type response header forbidden header name no syntax the clear-site-data header accepts one or more directives.
...if more data types are added in future versions of this header, they will also be covered by it.
...you can achieve that by adding the clear-site-data header when sending the page confirming that logging out from the site has been accomplished successfully (https://example.com/logout, for example): clear-site-data: "cache", "cookies", "storage", "executioncontexts" clearing cookies if this header is delivered with the response at https://example.com/clear-cookies, all cookies on the same domain https://example.com and any subdomains (like https://stage.example.com, etc), will be cleared out.

Content-Language - HTTP
the content-language entity header is used to describe the language(s) intended for the audience, so that it allows a user to differentiate according to the users' own preferred language.
...multiple language tags are also possible, as well as applying the content-language header to various media types and not only to textual documents.
... header type entity header forbidden header name no cors-safelisted response header yes cors-safelisted request header yes, with the additional restriction that values can only be 0-9, a-z, a-z, space or *,-.;=.
... <html lang="de"> do not use this meta element like this for stating a document language: <!-- /!\ this is bad practice --> <meta http-equiv="content-language" content="de"> indicating a target audience for a resource the content-language header is used to specify the intended audience of the page, and can indicate that this is more than one language.

Digest - HTTP
the digest response http header provides a digest of the requested resource.
...the selected representation depends on the content-type and content-encoding header values: so a single resource may have multiple different digest values.
... header type response header forbidden header name no syntax digest: <digest-algorithm>=<digest-value> digest: <digest-algorithm>=<digest-value>,<digest-algorithm>=<digest-value> directives <digest-algorithm> supported digest algorithms are defined in rfc 3230 and rfc 5843, and include sha-256 and sha-512.
... examples digest: sha-256=x48e9qookqqrvdts8nojrjn3owduoywxbf7kbu9dbpe= digest: sha-256=x48e9qookqqrvdts8nojrjn3owduoywxbf7kbu9dbpe=,unixsum=30637 specifications specification title draft-ietf-httpbis-digest-headers-latest resource digests for http this header was originally defined in rfc 3230, but the definition of "selected representation" in rfc 7231 made the original definition inconsistent with current http specifications.

Expect-CT - HTTP
the expect-ct header lets sites opt in to reporting and/or enforcement of certificate transparency requirements, to prevent the use of misissued certificates for that site from going unnoticed.
... be satisfied via any one of the following mechanisms: x.509v3 certificate extension to allow embedding of signed certificate timestamps issued by individual logs a tls extension of type signed_certificate_timestamp sent during the handshake supporting ocsp stapling (that is, the status_request tls extension) and providing a signedcertificatetimestamplist when a site enables the expect-ct header, they are requesting that the browser check that any certificate for that site appears in public ct logs.
... browsers ignore the expect-ct header over http; the header only has effect on https connections.
... header type response header forbidden header name yes syntax expect-ct: report-uri="<uri>", enforce, max-age=<age> directives max-age the number of seconds after reception of the expect-ct header field during which the user agent should regard the host of the received message as a known expect-ct host.

From - HTTP
the from request header contains an internet email address for a human user who controls the requesting user agent.
...a crawler), the from header should be sent, so you can be contacted if problems occur on servers, such as if the robot is sending excessive, unwanted, or invalid requests.
... you shouldn't use the from header for access control or authentication.
... header type request header forbidden header name no syntax from: <email> directives <email> a machine-usable email address.

Host - HTTP
the host request header specifies the host and port number of the server to which the request is being sent.
... a host header field must be sent in all http/1.1 request messages.
... a 400 (bad request) status code may be sent to any http/1.1 request message that lacks a host header field or that contains more than one.
... header type request header forbidden header name yes syntax host: <host>:<port> directives <host> the domain name of the server (for virtual hosting).

If-Match - HTTP
the if-match http request header makes the request conditional.
... there are two common use cases: for get and head methods, used in combination with a range header, it can guarantee that the new ranges requested comes from the same resource than the previous one.
... header type request header forbidden header name no syntax if-match: <etag_value> if-match: <etag_value>, <etag_value>, … directives <etag_value> entity tags uniquely representing the requested resources.
...however, in an if-match header, weak entity tags will never match.

Last-Modified - HTTP
the last-modified response http header contains the date and time at which the origin server believes the resource was last modified.
...less accurate than an etag header, it is a fallback mechanism.
... conditional requests containing if-modified-since or if-unmodified-since headers make use of this field.
... header type response header forbidden header name no cors-safelisted response header yes syntax last-modified: <day-name>, <day> <month> <year> <hour>:<minute>:<second> gmt directives <day-name> one of "mon", "tue", "wed", "thu", "fri", "sat", or "sun" (case-sensitive).

Location - HTTP
the location response header indicates the url to redirect a page to.
... all responses with one of these status codes send a location header.
...location is a header associated with the response, while content-location is associated with the entity returned.
... header type response header forbidden header name no syntax location: <url> directives <url> a relative (to the request url) or absolute url.

Public-Key-Pins - HTTP
note: public key pinning mechanism was deprecated in favor of certificate transparency and expect-ct header.
... the http public-key-pins response header used to associate a specific cryptographic public key with a certain web server to decrease the risk of mitm attacks with forged certificates, however, it has been removed from modern browsers and is no longer supported.
... use certificate transparency and expect-ct header instead.
... header type response header forbidden header name no syntax public-key-pins: pin-sha256="<pin-value>"; max-age=<expire-time>; includesubdomains; report-uri="<uri>" directives pin-sha256="<pin-value>" the quoted string is the base64 encoded subject public key information (spki) fingerprint.

Range - HTTP
the range http request header indicates the part of a document that the server should return.
... several parts can be requested with one range header at once, and the server may send back these ranges in a multipart document.
...the server can also ignore the range header and return the whole document with a 200 status code.
... header type request header forbidden header name no syntax range: <unit>=<range-start>- range: <unit>=<range-start>-<range-end> range: <unit>=<range-start>-<range-end>, <range-start>-<range-end> range: <unit>=<range-start>-<range-end>, <range-start>-<range-end>, <range-start>-<range-end> range: <unit>=-<suffix-length> directives <unit> the unit in which ranges are specified.

Sec-WebSocket-Accept - HTTP
the sec-websocket-accept header is used in the websocket opening handshake.
... it would appear in the response headers.
... that is, this is header is sent from server to client to inform that server is willing to initiate a websocket connection.
... header type response header forbidden header name no syntax sec-websocket-accept: <hashed key> directives <hashed key> the server takes the value of the sec-websocket-key sent in the handshake request, appends 258eafa5-e914-47da-95ca-c5ab0dc85b11, takes sha-1 of the new value, and is then base64 encoded.

WWW-Authenticate - HTTP
the http www-authenticate response header defines the authentication method that should be used to gain access to a resource.
... the www-authenticate header is sent along with a 401 unauthorized response.
... header type response header forbidden header name no syntax www-authenticate: <type> realm=<realm>[, charset="utf-8"] directives <type> authentication type.
... examples typically, a server response contains a www-authenticate header that looks like these: www-authenticate: basic www-authenticate: basic realm="access to the staging site", charset="utf-8" see also http authentication for examples on how to configure apache or nginx servers to password protect your site with http basic authentication.

X-DNS-Prefetch-Control - HTTP
the x-dns-prefetch-control http response header controls dns prefetching, a feature by which browsers proactively perform domain name resolution on both links that the user may choose to follow as well as urls for items referenced by the document, including images, css, javascript, and so forth.
... header type response header forbidden header name no syntax x-dns-prefetch-control: on x-dns-prefetch-control: off directives on enables dns prefetching.
... this is what browsers do, if they support the feature, when this header is not present off disables dns prefetching.
... examples turning on and off prefetching you can either send the x-dns-prefetch-control header server-side, or from individual documents, using the http-equiv attribute on the <meta> element, like this: <meta http-equiv="x-dns-prefetch-control" content="off"> you can reverse this setting by setting content to "on".

Getting started - SVG: Scalable Vector Graphics
for normal svg files, servers should send the http headers: content-type: image/svg+xml vary: accept-encoding for gzip-compressed svg files, servers should send the http headers: content-type: image/svg+xml content-encoding: gzip vary: accept-encoding you can check that your server is sending the correct http headers with your svg files by using the network monitor panel or a site such as websniffer.cc.
... submit the url of one of your svg files and look at the http response headers.
... if you find that your server is not sending the headers with the values given above, then you should contact your web host.
...if your server is not configured to send the correct headers with the svg files it serves, then firefox will most likely show the markup of the files as text or encoded garbage, or even ask the viewer to choose an application to open them.

How Mozilla determines MIME Types
however, starting in mozilla 1.7alpha, mozilla does do content sniffing, like this: when the content-type sent by the server is one of (case-sensitively) text/plain text/plain; charset=iso-8859-1 text/plain; charset=iso-8859-1 and the server did not send a content-encoding header, mozilla will sniff the first block of data it gets and check for non-text bytes.

Mork
the grammar for mork is as follows: file = header ( dictionary | table | group | row )* header = '// <!-- <mdb:mork:z v="1.4"/> -->' dictionary = '<' ( metadictionary | alias )* '>' table = '{' '-'?
... hex = [0-9a-fa-f]+ name = [a-za-z_?:] [a-za-z_?:+-]* value is a string terminated by ')' (not consumed) where '\' quotes the next metacharacter and '$' quotes the next two hexadecimal digits as a value (e.g., $20 is a space) the first line in the file is the header.
...the header is: // <!-- <mdb:mork:z v="1.4"/> --> this file is therefore version 1.4 of the zany mork format for the message database.

for example, the following document <html> <head> <title>my document</title> </head> <body> <h1>header</h1> <p>paragraph</p> </body> </html> has a dom tree that looks like this: (note that, although the above tree is similar to the above document's dom tree, it's not identical, as the actual dom tree preserves whitespace.) when a web browser parses an html document, it builds a dom tree and then uses it to display the document.
... a simple example suppose the author wants to change the header of the above document and write two paragraphs instead of one.
... the following script would do the job: html content <body> <input type="button" value="change this document." onclick="change()"> <h2>header</h2> <p>paragraph</p> </body> javascript content function change() { // document.getelementsbytagname("h2") returns a nodelist of the <h2> // elements in the document, and the first is number 0: var header = document.getelementsbytagname("h2").item(0); // the firstchild of the header is a text node: header.firstchild.data = "a dynamic document"; // now the header is "a dynamic document".

XHTML - Developer guides
the following example shows an html document and corresponding "xhtml" document, and the accompanying http content-type headers they should be served with.
...tml document</p> </body> </html> xhtml document content-type: application/xhtml+xml <?xml version="1.0" encoding="utf-8"?> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <title>xhtml</title> </head> <body> <p>i am a xhtml document</p> </body> </html> in practice, very few "xhtml" documents are served over the web with a content-type: application/xhtml+xml header.
... instead, even though the documents are written to conform to xml syntax rules, they are served with a content-type: text/html header — so browsers parse those documents using html parsers rather than xml parsers, which can cause a variety of sometimes-very-surprising problems.

Allowing cross-origin use of images and canvas - HTML: Hypertext Markup Language
html provides a crossorigin attribute for images that, in combination with an appropriate cors header, allows images defined by the <img> element that are loaded from foreign origins to be used in a <canvas> as if they had been loaded from the current origin.
... web server configuration the first thing we need is a server that's configured to host images with the access-control-allow-origin header configured to permit cross-origin access to image files.
...consider the html5 boilerplate apache server configuration file for cors images, shown below: <ifmodule mod_setenvif.c> <ifmodule mod_headers.c> <filesmatch "\.(bmp|cur|gif|ico|jpe?g|png|svgz?|webp)$"> setenvif origin ":" is_cors header set access-control-allow-origin "*" env=is_cors </filesmatch> </ifmodule> </ifmodule> in short, this configures the server to allow graphic files (those with the extensions ".bmp", ".cur", ".gif", ".ico", ".jpg", ".jpeg", ".png", ".svg", ".svgz", and ".webp") to be accessed cross-origin from anywhere on the internet.

... note: if the x-pingback: http header is also present, it supersedes the <link> element with this link type.

Compression in HTTP - HTTP
the browser sends an accept-encoding header with the algorithm it supports and its order of precedence, the server picks one, uses it to compress the body of the response and uses the content-encoding header to tell the browser the algorithm it has chosen.
... as content negotiation has been used to choose a representation based on its encoding, the server must send a vary header containing at least accept-encoding alongside this header in the response; that way, caches will be able to cache the different representations of the resource.
... to do this, http uses a mechanism similar to the content negotiation for end-to-end compression: the node transmitting the request advertizes its will using the te header and the other node chooses the adequate method, applies it, and indicates its choice with the transfer-encoding header.

Accept-CH-Lifetime - HTTP

CSP: upgrade-insecure-requests - HTTP
the upgrade-insecure-requests directive will not ensure that users visiting your site via links on third-party sites will be upgraded to https for the top-level navigation and thus does not replace the strict-transport-security (hsts) header, which should still be set with an appropriate max-age to ensure that users are not subject to ssl stripping attacks.

... header type request header forbidden header name no syntax upgrade-insecure-requests: 1 examples a client's request signals to the server that it supports the upgrade mechanisms of upgrade-insecure-requests: get / http/1.1 host: example.com upgrade-insecure-requests: 1 the server can now redirect to a secure version of the site.
... a vary header can be used so that the site isn't served by caches to clients that don’t support the upgrade mechanism.

X-XSS-Protection - HTTP
the http x-xss-protection response header is a feature of internet explorer, chrome and safari that stops pages from loading when they detect reflected cross-site scripting (xss) attacks.
... header type response header forbidden header name no syntax x-xss-protection: 0 x-xss-protection: 1 x-xss-protection: 1; mode=block x-xss-protection: 1; report=<reporting-uri> 0 disables xss filtering.
... example block pages from loading when they detect reflected xss attacks: x-xss-protection: 1; mode=block php header("x-xss-protection: 1; mode=block"); apache (.htaccess) <ifmodule mod_headers.c> header set x-xss-protection "1; mode=block" </ifmodule> nginx add_header "x-xss-protection" "1; mode=block"; specifications not part of any specifications or drafts.

HEAD - HTTP
the http head method requests the headers that would be returned if the head request's url was instead requested with the http get method.
... for example, if a url might produce a large download, a head request could read its content-length header to check the filesize without actually downloading the file.
...if it has one anyway, that body must be ignored: any entity headers that might describe the erroneous body are instead assumed to describe the response which a similar get request would have received.

Proxy servers and tunneling - HTTP
a common way to disclose this information is by using the following http headers: the standardized header: forwarded contains information from the client-facing side of proxy servers that is altered or lost when a proxy is involved in the path of the request.
... to provide information about the proxy itself (not about the client connecting to it), the via header can be used.
... via added by proxies, both forward and reverse proxies, and can appear in the request headers and the response headers.

Redirections in HTTP - HTTP
redirect responses have status codes that start with 3, and a location header holding the url to redirect to.
... when browsers receive a redirect, they immediately load the new url provided in the location header.
...machine-readable choices are encouraged to be sent as link headers with rel=alternate.

406 Not Acceptable - HTTP
the hypertext transfer protocol (http) 406 not acceptable client error response code indicates that the server cannot produce a response matching the list of acceptable values defined in the request's proactive content negotiation headers, and that the server is unwilling to supply a default representation.
... proactive content negotiation headers include: accept accept-charset accept-encoding accept-language in practice, this error is very rarely used.
... instead of responding using this error code, which would be cryptic for the end user and difficult to fix, servers ignore the relevant header and serve an actual page to the user.

412 Precondition Failed - HTTP
this happens with conditional requests on methods other than get or head when the condition defined by the if-unmodified-since or if-none-match headers is not fulfilled.
... status 412 precondition failed examples etag: "33a64df551425fcc55e4d42a148795d9f25f89d4" etag: w/"0815" avoiding mid-air collisions with the help of the etag and the if-match headers, you can detect mid-air edit collisions.
... for example, when editing mdn, the current wiki content is hashed and put into an etag in the response: etag: "33a64df551425fcc55e4d42a148795d9f25f89d4" when saving changes to a wiki page (posting data), the post request will contain the if-match header containing the etag values to check freshness against.

NSS 3.28.3 release notes
compatibility nss 3.28.3 shared libraries are backward compatible with most older nss 3.x shared libraries, but depending on your application, may be incompatible, if you application has been compiled against header files of versions 3.28, 3.28.1, or 3.28.2.
... if you had compiled your application against header files of nss 3.28, nss 3.28.1 or nss 3.28.2, it it recommended that you recompile your application against nss 3.28.3, at the time you upgrade to nss 3.28.3.

NSS 3.29.1 release notes
compatibility nss 3.29.1 shared libraries are backward compatible with most older nss 3.x shared libraries, but depending on your application, may be incompatible, if you application has been compiled against header files of versions 3.28, 3.28.1, 3.28.2 nss 3.29.1.
... if you had compiled your application against header files of nss 3.28, nss 3.28.1, nss 3.28.2 or nss 3.29, it it recommended that you recompile your application against nss 3.29.1 (or nss 3.28.3), at the time you upgrade to nss 3.29.1 (or nss 3.28.3).

Installation guide
our makefiles also have an "install" target, but it has a different meaning: our "install" means installing the headers, libraries, and programs in the appropriate directories under mozilla/dist.
... so right now you need to manually install the headers, libraries, and programs in the directories you want.

Sample manual installation
the nss build system does not include a target to install header files and shared libraries in the system directories, so this needs to be done manually.
... after building nss with "gmake nss_build_all", the resulting build can be found in the nss source tree as follows: nss header files: mozilla/dist/public/nss nspr header files: mozilla/dist/<obj-dir>/include nspr/nss shared libs: mozilla/dist/<obj-dir>/lib nss binary executables: mozilla/dist/<obj-dir>/bin.

sslintro.html
warning: some of the ssl header files provided as part of nss 2.0 include both public apis documented in the nss 2.0 documentation set and private apis intended for internal use by the nss implementation of ssl.
...other apis that may be exposed in the header files are not supported for application use.

Index
full documentation of how to define a jsnative (or a jsfastnative, the equivalent typedef which preceded it) is available in the api header "js/callargs.h" added in spidermonkey 24.
... this header is new, but the semantics it describes are applicable to all recent spidermonkey releases.

JSNative

... this header is new, but the semantics it describes are applicable to all recent spidermonkey releases.

Parser API
all binding forms (such as function parameters, variable declarations, and catch block headers) accept array and object destructuring patterns in addition to plain identifiers.
...in binding positions (such as function parameters, variable declarations, and catch headers), patterns can only be identifiers in the base case, not arbitrary expressions.

Gecko events
event_table_row_header_changed a table's row header changed.
...event_table_column_header_changed a table's column header changed.

ROLE_TABLE
« gecko roles page represents a table that contains rows and columns of cells, and optionally, row headers and column headers.
... also refer to the following roles: role_columnheader, role_rowheader, role_column, role_row, role_cell.

XPCOM glue
compiling or linking against xpcom headers there are three ways to compile/link against xpcom headers/libraries: frozen linkage: dependent glue (dependent on xpcom.dll) xpcom modules, i.e.
... sample compiler/linker flags code compiled using xpcom headers should always #include "xpcom-config.h" from the sdk, to ensure that xpcom #defines are correct.

Creating the Component Code
for example, mozilla_strict_api is a variable that shields you from certain private, non-xpcom headers.
... for example, including nsicomponentmanager.idl without mozilla_strict_api defined will include the following headers, which are not supported across versions (unfrozen): nscomponentmanagerutils.h nscomponentmanagerobsolete.h these variables are picked up by files that do not specify themselves as mozilla_strict_api.

Monitoring HTTP activity
tivityobserver = components.interfaces.nsihttpactivityobserver; var httpobserver = { observeactivity: function(ahttpchannel, aactivitytype, aactivitysubtype, atimestamp, aextrasizedata, aextrastringdata) { if (aactivitytype == nsihttpactivityobserver.activity_type_http_transaction) { switch(aactivitysubtype) { case nsihttpactivityobserver.activity_subtype_response_header: // received response header break; case nsihttpactivityobserver.activity_subtype_response_complete: // received complete http response break; } } } }; then you need to install your activity observer.
...these include the ability to monitor outgoing http request headers and bodies as well as incoming http headers and complete http transactions.
