Thank you for the fast reply. I am still full of questions. What are the advantage of using 'LB::server pool' over HTTP::host'? Testing the original script seems to work. Also does the order matter of how the rules are placed in iRules on the resource page of the virtual server list? Sorry if these seem like dumb questions, I am still trying to wrap my head around these F5's.
