redirect but keeping the original url

Hi

I managed to redirect HTTP request via another port. but I want to keep on the browser the orginial url.

for example: if i redirect the request: localhost:7020/blabla1/

to localhost:7010/blabla2 I dont want the user to see this url. I want to keep in the browser the original url.

I perform the redirect using a redirect rule.

another question.

What is the best way to map the urls from the pattern:

localhost:7020/myblabla/uniqueuesr1234 

I want based on the uniqueuesr1234 string to decide via which port i'll redirect my request.

corrently for every string i am making a new redirect rule.

Appreciate your fast reponse.
