Rewrite profile Issue

I have an issue with the URI rewrite profile. I believe it should be able to do what I need it to do, but can't get it working :(

 

I have a Virtual Server configured, lets call that DomainA, all our Virtual Servers have a client SSL profile.

 

I've created a URL rewrite profile as per the below;

 

• URI Translation
• Request Settings: Rewrite Headers, Insert X-Forwarded-For Header
• Response Settings: Rewrite Headers, Rewrite Content
• Rule Type = Both
• Client URI:
• Server URI:

That all works fine, I make a request and see the content that is in FolderB.

 

What I want to do is;

 

• URI Translation
• Request Settings: Rewrite Headers, Insert X-Forwarded-For Header
• Response Settings: Rewrite Headers, Rewrite Content
• Rule Type = Both
• Client URI:
• Server URI:

DomainB traffic goes to another Virtual Server on the same F5. When I test the above I get a response from a DomainA node saying FolderC does not exist.

 

I can successfully connect to directly, just not when using the rewrite profile.

 

We are running LTM 12.1.1. The reason for the rewrite profile is that we have an issue with a couple of web services were the sender can't handle a 301 or 302 redirect code - so we can't use redirects as part of the solution.

 

Any ideas?
