iRule for pool selection based on HTTP::URI

My default VS is "prod_vs" on 443 and default pool is "prod_pool" with 4 members (app{1-4}:7001). I'm doing SSL offloading on LTM. This has been working for me for years. Now I got a new requirements where I had to create a new pool "states_pool" and assign 2 members (app{4,5}:8080) under this pool. My goal is to if clients hit @ https://secure.mydomain.com then LTM would forward the request to "prod_pool" and if clients hit https://secure.mydomain.com/states/ then LTM would forward the request to "states_pool". Which is why I was trying to use the iRule.

With the iRule when I hit https://secure.mydomain.com it's working as expected but when I hit https://secure.mydomain.com/states/ it's being redirected to http://secure.mydomain.com.
