Problem while configuring the Apache Web Server as the Intermediary Server

Hello,

I want to use Apache 2.0 web-server as a proxy for my SAP EP so that I could access http://portal_server:50000/irj through this Apache external web-server.

I checked this sap help link as a reference.

http://help.sap.com/saphelp_nw04/helpdata/en/18/5cea2296190e4cb7faf9468ad793ea/frameset.htm

But still not clear what exact configuration I need to do in the httpd.conf file. I searched the posted forums on this topic but couldnt get exact steps.

It would be grateful if anyone can guide me on this configuration (redirecting url etc).

Thanks in advance.
