Inspect URI without Case Senstivity?

Hello all,     I have created the following rule to redirect traffic based on the URI to another pool, however, I want the rule to ignore case sensitvity within the URI string. Here is my rule:...
application delivery
dev
devops
iRules

matches_regex is way overkill for a simple string comparison. Regular expressions are very CPU intensive so it's better to not use them if you don't have to.

As for the case sensitivity, you can use the TCL "string tolower" command in your comparison. I'd go with something like this:

when HTTP_REQUEST {
  if { [string tolower [HTTP::uri]] starts_with "/_xml/ors/status.asp" }{
    pool mypool_B2B_SSL
  } else {
   pool mypool.com_SSL
  }
}

Hope this helps...
