I think you could modify Deb's last snippet to select a new pool:


when LB_SELECTED {
  if { $myretry >= 1 } {
    LB::reselect pool $my_new_pool
  }
}

You can test this by making requests which only generate a 500 response and see if the new pool is used.

Note that there is a known issue with LB::resleect. Check the wiki page (Click here) for related solutions which describe the problem.
