Where can I find the default timeout settings for all browsers?

by

I managed to find network.http.connect.timeout for much older versions of Mozilla:

This preference was one of several
added to allow low-level tweaking of
the HTTP networking code. After a
portion of the same code was
significantly rewritten in 2001, the
preference ceased to have any effect
(as noted in all.js as early as
September 2001).

Currently, the timeout is determined
by the system-level connection
establishment timeout. Adding a way to
configure this value is considered
low-priority.

It would seem that network.http.connect.timeout hasn’t done anything for some time.

I also saw references to network.http.request.timeout, so I did a Google search. The results include lots of links to people recommending that others include it in about:config in what appears to be a mistaken belief that it actually does something, since the same search turns up this about:config entries article:

Pref removed (unused).
Previously: HTTP-specific network
timeout. Default value is 120.

The same page includes additional information about network.http.connect.timeout:

Pref removed (unused).
Previously: determines how long to
wait for a response until registering
a timeout. Default value is 30.
