Note, that probably Zope user names may contain characters not allowed in Cookie values.

I wonder how hard it would be to implement the following: <dtml-var something cookie_quote> Quote all characters not allowed in a cookie <dtml-var somethinh id_quote> Quote all characters not allowed in a Zope 2.2 id (this one could be really handy ;-) cheers, Chris
