|   | 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. |

When `true`, allow the use of Perl-compatible or ECMAScript-compatible (IIS) regular expressions in [Not-Enforced URL List](com.sun.identity.agents.config.notenforced.url.html) settings.

Default: `false`
