>Release:        1.2.4 + SSL patches
>Environment:
Linux 2.0.32 (RedHat 4.2+), GCC 2.7.2
>Description:
Given a conf containing "ProxyPass /other.machine.edu http://other.machine.edu",
Apache 1.2.4 fetches & maps the following URL into the namespace of the current
server:

  https://current.server.edu/other.machine.edu/index.html <-
     http://other.machine.edu/index.html

Unfortunately, if http://other.machine.edu/index.html has any relative links
on it, they do not work.  For example, if http://other.machine.edu/index.html
has a link like <IMG SRC="/graphics/logo.gif">, this link should be mapped as
follows:

  /graphics/logo.gif ->
     https://current.server.edu/other.machine.edu/graphics/logo.gif <-
        http://other.machine.edu/graphics/logo.gif

Unfortunately, this is what happens:

  /graphics/logo.gif ->
     https://current.server.edu/graphics/logo.gif

Normally such mappings result in "broken" links.
>How-To-Repeat:

>Fix:
No suggestions; I'm only now looking at the source.  But I'd be happy to try
out patches for you, and try to work things out.

I feel really stupid - as if I've missed something obvious.  If so, then this
is a documentation bug, and not a software bug, seeing as I did not find a ready
solution to the problem in the documentation.

I'd be happy to help rewrite the relevant section of the docs, if that turns out
to be the problem.

Thanks...
