Newbie's Reverse Proxy problem

Hi folks,

I am new to Apache and to Linux.

I need to set up a reverse proxy with Apache2 and Linux (Suse 8.2). After
reading manuals and documentation (e.g.
http://httpd.apache.org/docs-2.0/mod/mod_proxy.html) I thought this would be a
pretty easy task - unfortunately it seems that I'm wrong....
After 3 days of try-and-error-and-search I am completely clueless...

What I want appears to me as a standard setup:
- 2 webservers inside the network (m01.mycompany.com, m02.mycompany.com)
- 1 reverse proxy (linux1.mycompany.com) on internet (secured)

The inside servers are mapped into the proxy server's the name-space:
http://linux1.mycompany.invalid/m01/ --> http://m01.mycompany.invalid/
http://linux1.mycompany.invalid/m02/ --> http://m02.mycompany.invalid/

I did all according to the reference configuration, however I did encounter a
problem:

When a page is viewd through the Proxy server, links on the root of the
destination are not correct.

The index.html of m01 contains a link to "/subdir/mypage.html".
The HTML code is: <A HREF="/subdir/mypage.html">My Page</A>
(I cannot change the code since it is generated)

The link should appear on the browser as pointing to
"http://linux1.mycompany.invalid/m01/subdir/mypage.html"
but it points to "http://linux1.mycompany.invalid/subdir/mypage.html"

So, the core proxy works, but the path of links is not build correctly (the
"/m01/" is missing)

Please find my config below. I don't want to use virtual hosts for several
reasons. Am I missing something? What is wrong?

Guido

The path isn't touched by the proxy, only the referrer and other stuff
in the header of the request are touched. If your page contains a
link to /something/ in the html code, it will be left untouched.

Nothing, this is how the proxy works. If you can't have the
application referring to himself as /m01/ it won't work.
