I read in the documentation that PCRE regex should be used. I believe the regex I have below should return true when the request url is “<a href="http://internal.my.com/any/thing" class="">http://internal.my.com/any/thing</a>” and the 15s ttl should be set. I’ve tried just (req.url ~ “<a href="http://internal.my.com" class="">internal.my.com</a>”) as well because I read that it should match if any part of the request url. Help is appreciated!
