Newbie Question

Roger,

first of all, it is generally better (read faster) to use the "equals", "starts_with", "contains" and "ends_with" operators instead of "matches_regex" unless you really need the full power of regular expressions. In you particular case I'd suggest to use:

if(http_uri contains "NewOrder") {
  use pool Idg_NewOrder_https
} else {
  use pool idg_443
}

It is impossible to tell what is failing from the data you've provided. I'd guess that your problem is in the matches_regex expression but I can't tell for sure, since you've not provided the URI that you've used to test your rule neither have you descibed what was the observed behavior.

In order to troubleshoot the problem, you can add log statements to your rule like this:

rule r1 {
  log "uri: " +  http_uri
  if(http_uri contains "NewOrder") {
    use pool Idg_NewOrder_https
    log "using pool Idg_NewOrder_https"
  } else {
    use pool idg_443
    log "using pool idg_443"
  }
}

You'll receive following log entries in /var/log/bigip when the rule gets executed:

RULE r1 - uri: NewOrder.asp?From=IDGC
RULE r1 - using pool Idg_NewOrder_https
