Does anyone have any information (such as a state diagram) of how a
browser request is fielded by Mozilla?
Specifically, I am wondering when entering a URL in the browser with
an IP address, how is the request handled versus providing a DNS name
in the URL? Where in the code does it determine if a DNS lookup is
required to serve the request or not?
To answer your specific question, most of the code doesn't care at all,
the determination happens pretty low in the stack:
http://mxr.mozilla.org/mozilla-central/source/netwerk/dns/src/nsHostResolver.cpp#556
In principle even this code wouldn't have to care and could just pass IP
address strings to getaddrinfo as well (and have the resolver worry
about that determination) but that fails on some platforms.
For your documentation question, try:
https://developer.mozilla.org/en/Document_Loading_-_From_Load_Start_to_Finding_a_Handler
https://developer.mozilla.org/en/The_life_of_an_HTML_HTTP_request
The second document is somewhat outdated in the details but is still
good enough for the big picture.
