nsIProtocolHandler
netwerk/base/nsiprotocolhandler.idlscriptable this interface is used to implement protocol handlers.

nsIIOService
inherits from: nsisupports last changed in gecko 1.2 this interface duplicates many of the nsiprotocolhandler methods in a protocol handler independent way (for example newuri() inspects the scheme in order to delegate creation of the new uri to the appropriate protocol handler).

this means that it should be possible to add new protocols to necko just by implementing nsiprotocolhandler and nsichannel.
...which one has to be used is defined by the implementation of nsiprotocolhandler for the scheme in question.

Necko Interfaces Overview
nsiioservice central necko service manages protocol handlers thin layer over protocol handlers provides interface for creating uri objects from uri strings maps uri scheme to appropriate nsiprotocolhandler impl nsiuri (nsiurl, nsifileurl, nsistandardurl) represents an uri, with getters and setters for various uri parts (eg.
...channel is used to download the resource once) download initiated via nsichannel::asyncopen method can be canceled via nsirequest::cancel method at anytime after invocation of asyncopen method nsiprotocolhandler a service that manages a protocol, identified by it's uri scheme (eg.

nsIProtocolProxyService
a proxy is disallowed, for example, if it is a http proxy and the nsiprotocolhandler for the queried uri does not permit proxying via http.
... if a nsiprotocolhandler disallows all proxying, then filters will never have a chance to intercept proxy requests for such urls.

The life of an HTML HTTP request - Archive of obsolete content
necko (the network library) checks the url scheme (the first part of the url, http: in this case) and locates the correct nsiprotocolhandler (in this case nshttphandler) and asks it for a nsichannel (nshttpchannel).

Limitations of chrome scripts
nsiprotocolhandler in multiprocess firefox, code which registers a custom protocol using nsiprotocolhandler must register the custom protocol in the child content process.

Necko Architecture
there are a minimum of two interfaces you need to implement in order to fit into the necko architecture: nsiprotocolhandler, and nsichannel.
