[Zope] Cookie Crumbler - Help modifying source

Hi all, I'm using Cookie Crumbler to authenticate users. On login failure, or success for that matter, Cookie Crumbler strips the request of all info. What I'd like it to NOT do is delete cookies I'm setting just before the user is required to login. I believe I'll have to modify the source code to be able to do this. I'm hoping someone could help me modify the source, and if there's a better way to go about achieving this, suggestions will be appreciated. Thanks in advance. Samir.
