Combine Two Rules Into One

You can do it several ways and the deciding factor is which makes more sense to you. Performance should be equivalent. Either of these should work

when HTTP_REQUEST { 
   switch [HTTP::host] { 
     "www.domain1.com" { 
       switch -glob [HTTP::uri] { 
         "/products*" { pool Altruik-Furniture } 
         default { pool Furniture-Production-Pool-HTTP } 
       } 
     } 
     "www.domain2.com" { 
       switch -glob [HTTP::uri] { 
         "/products*" { pool Altruik-CarpetOne} 
         default { pool CarpetOne-Production-Pool } 
       } 
     } 
   } 
 }

One question though. Is there a reason why you don't have the default pool setup for the virtuals in the virtual configuration? If you set the default for the domain1 virtual to Furniture-Production-Pool-HTTP and the default pool set for the domain2 virtual to CarpetOne-Production-Pool, then you could have an iRule that looks something like this

when HTTP_REQUEST [ 
   if { [HTTP::uri] starts_with "/products" } { 
     switch [HTTP::host] { 
       "www.domain1.com" { pool Altruik-Furniture } 
       "www.domain2.com" { pool Altruik-CarpetOne } 
     } 
   } 
 }

Lots of options, just pick one that works for you!
