No.
Yes.
Maybe.
The HTTPS protocol handles traffic destined for "port 443". This
protocol definition is applied to SecureNET and FWC traffic *only*.
CERN proxy client requests are handled by the Web Proxy Filter, which
natively understands HTTP and FTP as well as how to handle SSL tunnels
for HTTP. It *does not* use the protocol HTTP/HTTPS definitions.
If you bind the Web Proxy Filter to a non-cleartext HTTP
protocol or any
non-HTTP protocol, the Web Proxy filter will poop loudly in your
Cheerios.
As far as your inability to "configure HTTP" in your web publisihing
rules, I'd still like a TS to your machine. - something is very much
amiss.

Bottom line on this - tell me:
If you have "Web Filter" bound to HTTPS, can you make outbound HTTPS
connections?
That's really the whole question. On the network we're
seeing this on,
you cannot make outbound HTTPS connections if "Web Filter" is bound to
HTTPS. Let's start off in a simple manner, and see if that point is
true or not in your config please...

No, you need to configure the HTTP Security Filter, and
in order to configured the HTTP Security Filter, the Web Proxy Filter
must be enabled.
Its always enabled for Web listeners
It can unbound from the HTTP protocol, in which case the
configuration interface for the HTTP Security Filter
disappears, but you
configuration changes remain intact.
When you unbind the Web proxy filter from the HTTPS
protocol, no Web caching or filtering is done for Firewall clients or
SecureNAT clients.
Web proxy clients are always exposed to the Web proxy
filter, even if you unbind it from the HTTP protocol.
How's that?

If you're just publishing OWA and an RPC proxy
over HTTPS, isn't any filter configuration automatically
handled by ISA
when running the Publish Mail Server wizard? As I understood it, ISA
knows that stuff inherently; no configuration necessary.

We're all pendants here ;)
Here is my specific question then:
I want to publish HTTPS ie OWA for RPC and
HTTPS. I obviously need to
configure the HTTP Filter properties. If I have
the Web Filter bound to
HTTPS (iow, selected in the available filters
under the protocl config) then
ALL outbound HTTPS traffic breaks. Therefore,
one has to un-bind the Web
Filter from HTTPS for outbound to work (on this
install).
Ergo, since the Web Filter is not bound to the
HTTPS protocol (in order for
outbound to work), there is no way to select
"Configure HTTP" from the
properties of the web publishing rule.
FromwhenthouNowThinketh, WTF is the deal on what
properties of the filter
are applied? See what I mean??
