It is very easy to stop the password being sniffed, you just use https:// for cgiurl
(with appropriately configure server of course), and disallow access to the cgiscript
over http.
However the cookie is still sent for all requests, meaning that it could be stolen.
I don't know quite how well CGI::Session defends against this, but the best it could
do is probably tie it to an IP address, but that still leaves room for abuse.
I have created a patch that adds a config option sslcookie, which causes the
cookie to have it's secure property set. This means that it is only sent over SSL.
So if you can configure apache to do what you want, you only have to change two options
(cgiurl and sslcookie) to encrypt all authentication data.
The disadvantage is that if someone were to activate it while using http:// I think it
would mean they couldn't log in, as the browser would never offer the cookie.
I think I have made the documentation clear enough on this point.
