nope. it's off. here's config i'm using:
         UseCanonicalName        On
         CustomLog       /tmp/webmail.log combined
         ErrorLog        /tmp/webmail.log
         SSLEngine       Off
         RedirectPermanent /
         ProxyRequests Off
         ProxyVia Full
         ProxyPass /exchange/
         ProxyPassReverse /exchange/
         ProxyPass /public/
         ProxyPassReverse /public/
         ProxyPass /ex2k/
         ProxyPassReverse /ex2k/
         ProxyPass /exchweb/

'seems' to work means that if IE is directed through squid, i can login 
and navigate OWA; but inbox contents don't display and other little 
things seems broken, too.

this is apache 1.3.26 (with mod_ssl-2.8.10) on freebsd 4.6 stable built 
                 --prefix=/usr/local \
                 --server-uid=www \
                 --server-gid=www \
                 --with-perl=${PERL} \
                 --with-layout=FreeBSD \
                 --without-confadjust \
                 --enable-module=most \
                 --enable-module=auth_db \
                 --enable-module=mmap_static \
                 --disable-module=auth_dbm \
                 --enable-shared=max \
                 --enable-module=ssl \

                 -DHARD_SERVER_LIMIT=512 \
                 -DDOCUMENT_LOCATION=\\"/usr/local/www/data/\\" \
                 -DDEFAULT_PATH=\\"/usr/local/bin:/bin:/usr/bin\\" \

with FBSD's kernel AACF modules installed.

furthermore, I rebuilt everything this morning just to be sure.

is this supposed to work? has anyone successfully proxied owa/iis 
through apache-1.3.26 ?
