title: String modification in APIGEE edge without using Javascript
body: <p>I was wondering on there was an keyword like lower() in apigee edge to change the value to lowercase to check in conditional flow</p>
  <p><a href="http://api.com/%7Buriparam%7D?Action=Lower" rel="nofollow noreferrer">http://api.com/{uriparam}?Action=Lower</a></p>
  <p>lower(request.queryparam.Action) == &quot;lower&quot;</p>
  <p>is there any way to achieve this without using any java script?</p>
