Proxy server with Apache

[Andreas Tille <tillea@rki.de>]

Hello,

I want to set up my Apache seerver as Proxy host.
I'm really unexperienced in this topic and at first I
want to describe my environment:

There are different departments in our institute.
The main department has a fast internet connection and
uses a firewall and a proxy server.

I work in a department with a slow connection (modem line)
to the main department.  We are sitting behind the firewall.

My idea was to speed up the internet connection using a
local proxy server in our house to serve visited sites for
all user via local net.

I tried it setting up the Apache server and commented out the
line 

LoadModule proxy_module /usr/lib/apache/1.3/libproxy.so

in /etc/apache/httpd.conf.  After that I did

  /etc/init.d/apache restart

You guess it or not, it doesn't work.  Could someone enlighten
my why not.

Kind regards

       Andreas.
