On IBM Websphere 7.0 all session cookie related test cases might fail. This happens because of the following bug in Websphere
Here are some details :
Based on RFCs, the cookie expire date format is DD-Mon-YYYY HH:MM:SS GMT. (RFC 822, RFC 850, RFC 1036, and RFC 1123)
But in WebSphere 7 it comes as DD-Mon-YY HH:MM:SS GMT
So on the browsers which doesn't recognize this expire date format, ColdFusion administrator and other session related stuffs (which uses session cookies) may break.
