I know how it generally works; I was asking William for his scenario...

Jim,
If a user tries to go to a disallowed site they will get the "page
cannot be displayed" screen or if you have setup the rule to redirect to
a certain page the user will get that page. For example I have my
disallowed sites redirected to "isaserver.org.

Here's another question:
If a user tries to go to a disallowed site, do they get reprompted or
simply denied?

OK, I hear you. But if I tell you that the only difference between 2
usernames is that the one has an S&C rule with a limited destination set
(which includes the www.<domainname>.co.za that I am trying to access),
and
the other has an S&C rule with an "Any Site" S&C Rule, then I'd would
like
to hear your thoughts on this.
Tom's comment about users requiring "Full access" to the SSL server
confuses
me, as the only Full Access that I can think of is to give these users
an
"Any Site" S&C Rule as that is the only difference between these
users...
but this doesn't make sense to me.
As you rightly pointed out, 12209 indicates that there was a Proxy Auth
failure, which is maybe what Tom was talking about regarding the Full
Access
for SSL, but I'm damned if I know where to investigate this further...
If you have any pearls of wisdom I will gladly accept them :)
Cheers
William R.

Hi William,
I haven't followed the thread as Tom was handling your issue.
If I can take you back in time, those log entries are pretty clear to
me:
(first entry): the sc-result code is 10054. This is a Winsock response
meaning the connection, although initially accepted (listener
responded),
the connection was dropped (reset) afterwards. Since this appears to be
an
SSL connection (SSL-tunnel), there may have been a problem in the SSL
handshake.
(second entry): the sc-result code is 12209. This is a proxy auth
failure.
Since there was no allowed traffic, there is no rule to quote.

Jim, it looks like Tom is probably getting some well deserved rest as I
haven't seen a post from him for a few days now. Would you perhaps have
any
insight for me into the matter Tom highlighted with regards my SSL
issue?
See below for more info...

Hi Tom
When you say users require "Full Access" to the SSL Server, how would
you
propose I implement this? I can think of no other way to do this other
than
giving these users access to a S&C rule that allows ALL destinations...
and
this doesn't make sense to me...?
Your thoughts?

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.
