 HTTP::header replace "Host" "sample.com"
 set new_uri "/api/v2/widgets[string range [HTTP::uri] 12 end]&account_id=5036&domain_key=example"
 log local0. "new_uri: $new_uri"
 HTTP::uri $new_uri

Sanjay,

 

The iRule is doing his job, by re-writing exactly, how we wanted. However, the page is not loading automatically (or using the incoming URL). When we try manually with a new URL (Enabled log, so I was able to get the new URI) in the browser it is loading. The pool is also reachable from LTM.

you would need to capture tcpdump, enable logging in iRule to capture request and response and also review devolper tool logs from the browser to see what's happening.
