Change URI without redirect

The first if-clause is to capture http://www.abc.com/demo

 

The secondd if-clause is to capture http://www.abc.com/demo/ or http://www.abc.com/demo/xx/yy.html etc

 

 

I will get redirect one time only no matter which case it is. However we don't want that redirect because it is redirect back to bigip itself. It would be much more efficient to change the URI and forward to a pool immediately, rather than get back the redirect to client and client initiate a new request to match the last else-clause.
