IRules setting for http redirect then rewrite response

I am working with Oracle istore behind an F5 and basically we are trying to use the F5 as a reverse proxy and do something like this.

 

 

customer url: http://istore.cust.com

 

actual oracle istore url: http://hostname:8000/OA_HTML/ibeCAcdLogin.jsp?a=b

 

 

I wrote a rule to make the F5 forward requests from the customer to the actual url, but the customer sees the http://hostname:8000/OA_HTML/ibeCAcdLogin.jsp?a=b as the response of the redirect. How can I clean this up to make it pretty to the customer? I would like the customer to either only see the page as http://istore.cust.com or http://istore.cust.com/OA_HTML/ibeCAcdLogin.jsp?a=b but not as the actual hostname with the port 8000.

 

 

here is what I have for irules so far:

 

 

when HTTP_REQUEST {

 

HTTP::redirect "http://hostname:8000/OA_HTML/ibeCAcdLogin.jsp?a=b"

 

}
