With version 0.5.0 I introduced a plugin probe system which allows to interpretate the response of a probe in a custom way.

Possible are fingerprints of the response body, the response code and the response headers. This allows to detect a lot of different services running on remote hosts.

A basic Apache plugin is included in the source code. You can find it in the plugins directory.
