Subject RE: Cookie matcher
Date Fri, 19 Oct 2001 11:09:37 GMT
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).

Carsten
