IRule help

I have JDedwards installed on 2 servers under Oracle application server.

 

I have created a virtual server that point to pool of IP addresses pointing to these 2 servers.

 

 

My virtual address is http://erpdev.abc.com

 

annd my 2 servers jde url is http://server1.abc.com/jde/E1Menu.maf and http://server2.abc.com/jde/E1Menu.maf.

 

 

First I want to make sure that the user load is balanced between these 2 servers and also when a user logs into http://erpdev.abc.com it should reslove to one of these servers but keep the server name hidden for eg it should navigate through jde as http://erpdev.abc.com/jde/E1Menu.maf, so its trasparent to the user what jde webserver he is connected to.

 

 

Any help in genrating a irule to accomplish this would be highly appreciated.

    When you tested this, without an irule, did you see the URL change from http://erpdev.abc.com to http://serverX.abc.com...?
