I have found that my usage of Comet (and perhaps anyone's usage of Comet)
doesn't play well with certain AV programs and software firewalls.
Specifically I am using Kaspersky Internet Security Suite 7.0. I found that
if I enable web anti-virus detection then Comet gets blocked unless I add
the URL into the trusted sites. It seems that the AV program can detect
that the traffic over the HTTP port is not true HTTP by using heuristics and
thus suspects it's a virus. Also, anti-banner protection blocks it in a
similar manner.
This is actually a serious problem as I don't want people to go to my
website and find it doesn't load at first attempt for these reasons as they
will probably never come back and they certainly won't fiddle with their AV
or firewall until it works.
Any thoughts?
