Hello,

Are you sure that you don't have an "absolute link" in your application that redirect user on port 80. After you try to reach it in port 8080...

Set your Vs port to 8080 and stick this following irule then check logs in cli:

tailf /var/log/ltm

when HTTP_REQUEST {
   set LogString " Client [IP::client_addr]:[TCP::client_port] -> [HTTP::host][HTTP::uri]"
   log local0. " ============================================="
   log local0. " $LogString (request)"
   foreach aHeader [HTTP::header names] {
      log local0. " $aHeader: [HTTP::header value $aHeader]"
   }
   log local0. " ============================================="

}

when HTTP_RESPONSE {
   log local0. " ============================================="
   log local0. " $LogString (response) - status: [HTTP::status]"
   foreach aHeader [HTTP::header names] {
      log local0. " $aHeader: [HTTP::header value $aHeader]"
   }
   log local0. " ============================================="   

}

This Irule will help you to log all your header and will help us to find/identify the problematic.

let me now about logs....
