Hi Zenato. You probably don't need an iRule for this. You didn't specify what kind of HTTP server you are using, but it is important to create/add a Virtual Host definition on each server in the pool. The big-ip Virtual Server represents 2 or more physical servers. So to keep the Hostname portion of the URL from changing, OHS and Weblogic allow you to add a Virtual Hostname to each server. Here are some links to get you started, your Web server Admin should know how to do this stuff.

 

http://docs.oracle.com/cd/E12839_01/core.1111/e12035/webtier_im.htm

 

http://docs.oracle.com/cd/E14571_01/apirefs.1111/e13952/taskhelp/virtual_hosts/VirtualHosts.html

 

If that does not work ( because your HTTP servers are old ), then you could try a big-ip STREAM profile, that will re-write the hostnames on the fly. You can check out the stream profile here:

 

https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm_concepts_11_0_0/ltm_other_profiles.html1206878

 

There is an example of using the Stream Profile with WLS in this deployment guide:

 

http://www.f5.com/pdf/deployment-guides/iapp-weblogic-dg.pdf

 

If none of that works, then you will need to write an iRule, and search Devcentral Codeshare for an example of Host re-write.

 

Good Luck,

 

Chris.

Hi Chris, thank you for the response. I'm using apache-tomcat-6.0.35 http server. I use stream profile, it succeed but can only replace one IP address. in my problem i have 2 source address (10.251.227.1 & 10.251.227.2). in stream profile i can only modify from 10.251.227.1 to 10.251.227.231, but i can't modify from 10.251.227.2 to 10.251.227.231.
