node selection string from v 4.x to v 9.x

Hello Vasile,

It would be helpful to get more detail on what wasn't working and what errors you saw. You could provide any relevant errors from /var/log/ltm using the current rule, or add log statements to the rule to get additional debug information.

I believe there are a couple of minor typos in the rule which may have prevented it from working as expected. There was a missing close parenthesis and myNodeIP was originally set as myNode. Try this and see what the results are:

when HTTP_REQUEST {
   log local0. "starting..."
   set myNodeIP [findstr [string tolower [HTTP::uri]] "?ip=" 4 "/"]
   if { $myNodeIP ne "" } {
      log local0. "myNodeIP: $myNodeIP"
      pool http_pool $myNodeIP 80
   }
   else {
      log local0. "myNodeIP was empty: (myNodeIP: $myNodeIP)"
   }
}
when LB_FAILED {
   log local0. "LB failed!"
   LB::reselect
}
