Java2Script is blocked

[Sathya]

Dear Developers,

Java2Script.org was a wonderful url to access the google chat from
office. As the number of hits to this proxy site became high. They
have blocked this site also. Here they must be using some kind of web
sense. As soon as they find something like Java2Script in the url.
They are blocking it. Not even urls with im extention are being
allowed.

Kindly provide any other url which websense should not detect and we
should be able to access gtalk/gmail from office.

Thanks and Regards,
Sathya
