Hi Kevin,

I think this will work for you. If you run into any issues, check /var/log/ltm for debug output. You can add more debug statements to see what's happening. Once you're done testing, you can comment out the log statements to save resources. 

 
 when HTTP_REQUEST { 
  
    log local0. "[IP::client_addr]:[TCP::client_port]: New request to [HTTP::uri]" 
  
     Check if URI contains /forms 
    if {[HTTP::uri] contains "/forms"} { 
  
       log local0. "[IP::client_addr]:[TCP::client_port]: active members: [active_members SECOND_POOL]" 
  
        Use the second pool if it has available members 
       if {[active_members SECOND_POOL] > 0}{ 
          pool SECOND_POOL 
  
       } else { 
           Second pool was down, so use the third pool 
          pool THIRD_POOL 
       } 
    } 
 }
