Hi William,

Users must have full access to the server to which they create an SSL
connection because they cannot evaluate the path. If you have a path in
the rule allowing them access, then the connection request fails. Even
the dreaded /* can create this problem.

HTH,
Tom

Hi there

I have some users who are "not allowed" to access the Internet. But
being the nice guy I am I managed to get management to approve the
"opening" of certain sites, such as the medical aid and pension scheme
websites. So to do this I created an S&C rule to allow the necessary
destination sets for all Domain Users. The trick with this is that the
Medical Aid website works just fine, but the Pension website doesn't. I
have now managed to figure out that the problem is related to the fact
that the Pension website is an HTTPS secure site. In fact, any HTTPS
site that I "open", the users keep getting prompted for their
credentials, but any other HTTP website works just fine.

Here are the excerpts from the WEB log (I've removed all the unnecessary
info):
Medical Aid
<clientIP>, WillTest, Mozilla/4.0 etc etc, 11/25/2003, 15:35:57,
w3proxy, <FIREWALL>, -, www.sovhealth.co.za, 196.37.176.210, 80, 2953,
455, 0, http, TCP, GET,
http://www.sovhealth.co.za/web/images/background.gif, image/gif, Inet,
10054, 0x801002, pWEB Protocols, scWEB - Free Sites

Pension Scheme
<clientIP>, WillTest, Mozilla/4.0 etc etc, 11/25/2003, 15:35:58,
w3proxy, <FIREWALL>, -, www.mebmac.co.za, -, 443, 0, 0, 0, SSL-tunnel,
TCP, -, www.mebmac.co.za:443, -, Inet, 12209, 0x0, pWEB Protocols, -

As you can see, the Pension website doesn't find a matching Rule 2 (Site
& Content Rule), and this I cannot understand. Is it possible to declare
HTTP and HTTPS website distinctions in the Destination Sets?

Cheers
William R.
