I am having a problem with cookies in Internet Explorer. Zope will not allow cookies in IE to have -'s or ,'s. The problem extends from the fact that IE does not quote the environment variable HTTP_COOKIE, so Zope has separate regular expressions to deal with HTTP_COOKIE in Netscape and IE when parsing HTTP_COOKIE into the cookies dictionary. This is handled in the parse_cookie method of HTTPRequest.py. The first reg exp below is for Netscape and the second is the one it uses for IE. I understand why the one for IE does not allow for spaces, \0's, "'s, and ;'s because those are possible delimeters of the end of a cookie value, but I do not understand why it excludes -'s and ,'s. Does anyone know the reasoning behind this? qparmre=regex.compile( '\([\0- ]*' '\([^\0- ;,=\"]+\)="\([^"]*\)\"' '\([\0- ]*[;,]\)?[\0- ]*\)' ) parmre=regex.compile( '\([\0- ]*' '\([^\0- ;,=\"]+\)=\([^\0- ;,\"]*\)' '\([\0- ]*[;,]\)?[\0- ]*\)' )
