...just to find out what the table is about, he or she can rely on a caption and then decide whether or not to read the table in greater detail. a caption is placed directly beneath the <table> tag. note: the summary attribute can also be used on the <table> element to provide a description — this is also read out by screenreaders. we'd recommend using the <caption> element instead, however, as summary is deprecated by the html5 spec, and can't be read by sighted users (it doesn't appear on the page.) active learning: adding a caption let's try this out, revisiting an example we first met in the previous article. open up your language teacher's school timetable from the end of html table basics, or make a local copy of our timetable-fixed.html file. add a suitable caption for the table. ...

What is RSS - Archive of obsolete content
it is almost always created by server-side software (usually written in a language like php, java, c#, or python) on the web server. however, so that we can learn rss, we will be creating rss scripts by hand. a short history of rss in march of 1999 netscape released rss 0.90. it was much much different than today's rss. it wasn't really a format for syndication, but was a format for providing a summary of a website. in fact, back then, rss did not stand for really simple syndication but stood for rich site summary. in july of 1999 netscape's rss 0.91 was released. like rss 0.90, netscape's rss 0.91 was also a format for providing a summary of a website, and not really a syndication format (as it is today). netscape's rss 0.91 was created to simplify things. rss 0.90 was rdf-based, which many f...

he, the session cache needs some additional information that identifies that server. this additional identifying information is known as a peer id. the peer id is associated with a socket, and must be set before the ssl handshake occurs--that is, before the ssl handshake is initiated by a call to a function such as pr_read or ssl_forcehandshake. to set the peer id, you use ssl_setsockpeerid. in summary, ssl uses three pieces of information to identify a server's entry in the client session cache: the hostname, port number, and peer id. in the case of a client that is tunneling through a proxy, the hostname and port number identify the proxy, and the peer id identifies the desired server. netscape recommends that the client set the peer id to a string that consists of the server's hostname and p...
