proxypass irule 302 redirect

I have the proxypass rule working to do mostly what I want to do. Here is what I need to accomplish. When users go to www.abc.com/r the Irule I have setup as follows /r site.myserver.com/redirect mypool 64.64.64.64. There is a redirect on the IIS server myserver.com that goes to google. The site redirects but changes my url to www.google.com. For anything else /s site.myserver.com show the site.myserver.com webpage with my original url. I have the http profile setup to rewrite all. Any pointers would help.

 

 

I have attached the log from enabling debugging.
