Subject [users@httpd] Exchange 2K OWA w/IE clients
Date Thu, 18 Sep 2003 18:46:31 GMT
A client of ours recently (last weekend) migrated to Exchange 2K, from
Exchange 5.5.

Before the migration apache proxied Exchange 5.5's OWA just fine with a
simple rewrite rule.

After the upgrade it didn't work. So we did a little research and came
up with the following directive set that works for NON-IE clients (i.e.
it works fine with Mozilla/FireBird, Opera seems to have the same
problem as IE though regardless of Identify string):

ProxyPreserveHost On
RequestHeader set front-end-https: on
ProxyPass /exchange http://172.19.2.10/exchange
ProxyPassReverse /exchange http://172.19.2.10/exchange
ProxyPass /exchweb http://172.19.2.10/exchweb
ProxyPassReverse /exchweb http://172.19.2.10/exchweb
ProxyPass /public http://172.19.2.10/public
ProxyPassReverse /public http://172.19.2.10/public

The 172.19.2.10 IP is their exchange server sitting on a private subnet
behind the firewall.

The HTML passed to IE/Opera is different than the HTML passes to
Mozilla/Firebird. The HTML itself loads okay (with a single
authentication check), but I seem to get an authentication check for
each <img/> that is being loaded in the IE page. I took a look at the
HTML and the <img/>'s src is all withing the Proxied space so it's a
little confusing.. For instance...

One of the images is https://<webserver>/exchweb/img/tool-move.gif,
which should just be proxied without problems AFAICT.

Even if I put in the proper credentials for each img the img still
doesn't load.

Oh, and we did turn off windows integrated authentication as well.

Has anyone run into this? Does anyone know what we are doing wrong?

Thanks,
