I tried this on BigIP 12.1.4. I was testing with recaptcha_session_timeout set, and saw line 136 throwing an error. Adding curly braces around this expression resolved the issue:

 

{ [clock seconds] + $static::recaptcha_session_timeout }

 

HTH anyone else using this script.

 

With this one correction, works as expected. With the cookie in play, and conditional statements at the top of the HTTP_REQUEST section, I anticipate we can fine-tune access control over individual portions of the web site. Thank you for providing this.
