Re: blocking Google Desktop

[sekure <sekure () gmail com>]

I believe it is per TCP session, but don't quote me on that.  Actually
now that i think about it, if it indeed is per TCP session then the
second rule will not trigger, since the SSL connection will be a part
of a different session.

I am not 100% sure though.  Try it out and let us know. You might want
to post to snort-sigs or snort-users and see if they are more helpful.
