|   | Regular expressions are evaluated differently by different engines. When you use regular expressions in not-enforced lists, make sure that the expressions are evaluated in the way you expect. Double check that the correct URLs are enforced and not enforced. |

A flag to enable [Perl-compatible regular expressions](http://www.pcre.org/pcre.txt) or [ECMAScript-compatible](https://en.cppreference.com/w/cpp/regex/ecmascript) (IIS) in [Not-Enforced URL from IP Processing List](org.forgerock.agents.config.notenforced.ipurl.html).

Default: `false`
