Forwarding to server, "pool" versus "virtual"

Hi all,

I have an issue with an irule and maybe someone has an idea of what’s wrong ..

The virtual server “myServer” has a default pool “myPool” which has a single member - all of these are marked as up.

The flow is as follows:

  1. request comes in
  2. payload is HTTP::collected, parsed and modified using a sideband connection to another virtual server
  3. new payload is constructed and replaces the old HTTP::payload using “HTTP::payload replace”
  4. iRule is finished and new HTTP::payload should be load-balanced to the single member

However, although the member is selected correctly (as seen in the LB_SELECTED {} event) no connection is attempted to it, after a relatively long timeout LB_FAILED triggers.

  • I have tried specifying the pool in the iRule as well - “pool myPool” - with the same results

  • if I set up a dummy virtual server though and use “virtual myServer2” then traffic is forwarded instantly

Can anyone explain why no connection would be made to the pool member?

Thanks!

I think you need to provide your iRule for someone to help out. Also, did you check the logs to see if there are any error logs ?
