Preserving ToS over the duration of a download

Hi Jonathan,

If you don't have a OneConnect profile associated with the virtual server, you should be able to use a rule like this to keep the same pool selected after an HTTP request contains wmv in the path. Make sure to comment out or remove the logging once you're done testing.

when CLIENT_ACCEPTED {

    Save the name of the default pool before it is modified in the rule
   set default_pool [LB::server pool]
   log local0. "[IP::client_addr]:[TCP::client_port]: Default pool: $default_pool"
}
when HTTP_REQUEST {

    Check if request is for a wmv file
   switch -glob [string tolower [HTTP::path]] {
      "*.wmv" {
            pool tos-40-pool
            log local0. "[IP::client_addr]:[TCP::client_port]: Selected: [LB::server] for wmv request"
            if { ![LB::status up] }{
               log local0. "[IP::client_addr]:[TCP::client_port]: Pool not up, dropping connection"
               drop
            }
         }
      }
      default {
         log local0. "[IP::client_addr]:[TCP::client_port]: Non-wmv file, detaching"
         LB::detach
      }
   }
}
 Debug events only.  Comment out or remove once done testing.
when LB_SELECTED {
   log local0. "[IP::client_addr]:[TCP::client_port]: Selected: [LB::server]"
}
when SERVER_CONNECTED {
   log local0. "[IP::client_addr]:[TCP::client_port]: Connected: [IP::server_addr]:[TCP::server_port]"
}
