Can3can3can3.
Configured per your instructions; Web Proxy bound only to HTTP protocol.
Tom is correct; the Web Proxy *must* be bound to the HTTP Protocol, and
it *must not* be bound to the HTTPS protocol.

Right- so to Jim with his "can2, can2, can2" i have to say, "ni"
 
Can't config HTTP on the rule if HTTP or HTTPS (respectively) is not
bound to "Web Filter."  My machine is not bursted in that regard.
 
Now, when you say "Still working" what does that mean?  HTTP Filter
configurations are rule-based.  Are you saying if I un-bind Web Filter
from HTTP and HTTPS on a fresh install, and then create a pub rule, that
some "general, default" HTTP filter config is still applied to Web Pub
rules?

        When you unbind the Web Proxy filter from the HTTP protocol your
HTTP Security Filter configuration options go away, but they're still
working.

                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??
