IIS7.5 - Reverse proxy - defined, but doesn't work, why?

I used the following link to defined Reverse proxy

http://blogs.iis.net/carlosag/archive/2010/04/01/setting-up-a-reverse-proxy-using-iis-url-rewrite-and-arr.aspx

Installed:
•Install URL Rewrite 2.0
 •Install Application Request Routing

Configured 2 IIS servers as:
1st - as Reverse proxy according to the article but for my site - this IIS server should rewrite URL to the second's server site according to the rule I defined
2nd - defined some site that should accept rewrited requests.

But rewrite actually doesn't happens.

Please advice how to check.
