Slight modified existing iRule. you can write something like below....

    when RULE_INIT {
     Change to "1" to enable debugging log statements
    set static::Poolxyz_select_debug 0
  }

when HTTP_REQUEST {
    if {[string tolower [HTTP::host]] contains "api-dev" } {
     switch -glob [string tolower [HTTP::uri]] {
      "/someuri" { pool XYZ }
       default     { pool big_pool }
    }

    if { $static::Pool_select_debug eq 1 } {
    log local0. "[IP::client_addr] with URI of [HTTP::uri] went to XYZ Pool" 
             } 
        }
 }

Thank You for the quick response. It looks like this above IRule is working, I do not see the failures on the Statistics Tab. But on the /var/log/ltm, It is hard to trace the URI being redirected to diff pool. Because Other URIs which we did not mention in the Irule also logged as IP with /xyz or /someuri went to the XYZ Pool. It would be easier if we set up a variable for the Pool.

 

Thank You again for the help.
