AdIDoS and WCF web services

[kmzs]

Attacking a WCF web service with attacks like Element Count, Hash Collision or XML Overlong Names results in a not successful attack and the log entry:

WARN [PossibleState] Service seems to be down! No request was send successfully. Abort execution.

This error message implies that there was a problem with the service´s availability although the service was available all the time and answered the requests with a HTTP status code "413 Request Entity Too Large".
The plugin should recognize the HTTP code in the answer and therefore stop the attack and give a 0% rating. The error message is not needed/not correct and might confuse the user.

This can be reproduced using the "WCF-1" sample web service.
