Cookie matcher
Hi all ..
I've not found a simple way to match against a cookie, it should be
possible with matching the headers, but since it's a bit confusing and
error prone, I've cloned the RequestParamMatcher and modified it in the
RequestCookieMatcher .. I've not tested it too much .. but it seems to work
.. and since it's 99% copied from the RequestParamMatcher class it should
be ok ... here is the source :

Hope it will be useful ...
Congratulations from this great piece of software !

RE: Cookie matcher
Posted by Carsten Ziegeler <cz...@sundn.de>.
Hi Simone,
thanks for your contribution! If noone else is integrating
your patches in the next days, I would ask you to add
these to bugzilla as an enhancement so that they don't get
lost. (Unfortunately, I don't have time to look at it).
