[Zope] SiteAccess 2.0b3 missing setURL?

This seems to be missing in this version of site access. I am followig the url based session howto. There is a file ChangeBehaviors.py in the SiteAcces 1.x versions that seem to be missing in 2.0b3 that defines this function. An oversight or is there a change in API? Zope version: Zope 2.2.1 (binary release, python 1.5.2, solaris-2.6-sparc) Regards, Albert Boulanger aboulanger@ldeo.columbia.edu
