help with proxy configuration

Hello,

this is maybe a stuiped question, but I am new to apache and I have a
problem to setup my proxy. I used the simple example from the manual:

Forward Proxy
ProxyRequests On
ProxyVia On

<Proxy *>
Order deny,allow
Deny from all
Allow from all
</Proxy>

If I now use this proxy (installed on machine A) from machine B I have
a strange effect. Instead of getting the requested web page (e.g.
www.google.com) I get the start page of the proxy. Can anyone please
tell me how I can solve this?

thank you
Oliver
