Hi George,

There are quite a few examples in the forums and the iRules wiki of iRules which check the host (retrieved using HTTP::host Click here) and the URI (retrieved using HTTP::uri Click here).

Here is one example of checking the host and URI to select corresponding pools: 

 
 when HTTP_REQUEST { 
  
     This event is triggered when LTM parses the HTTP request headers 
  
     Check requested host using lower case 
    if {[string tolower [HTTP::host]] eq "subdomain.example.com"}{ 
  
        Check the requested URI 
       if {[HTTP::uri] starts_with "/some_uri"}{ 
           pool some_pool 
       } else { 
           pool other_pool 
       } 
    } else { 
       pool some_other_pool 
    } 
 }
