New to iRules and trying to get port translation to work

Thanks, I'll give this a try. To answer your question this is the actual url that should take me to the back end server on port 57070 http://swfm1.dev.mesaaz.gov/fm_http/

See the customer enters this from the Internet in their browser then hits the VIP solidwaste.mesaaz.gov within that VIP is the iRule so basically all 3 url's go to the same VIP but have different pools to be directed to. Hope that helps.
