Nick...you're my hero! This looks like it's going to work wonderfully.
The rewrite directive is still a bit mysterious to me right now, but I'm
sure I'll get the hang of it in time. A big thank you for helping to solve
this issue.

Re: [users@httpd] ProxyPass with
Please respond to exceptions
users@xxxxxxxxxxx
e.org
I just had a similar problem. What is happening is as follows....
ProxyPass /cob http://192.168.1.1/cob
ProxyPassReverse /cob http://192.168.1.1/cob
catches /cob, but not cob/webappage.nsf
the proxypass is working on the directory level only and not whats
below it in the directory tree.
So ...
ProxyPass / http://192.168.1.3/
ProxyPassReverse / http://192.168.1.3/
is actually catching /cob/webappage.nsf
The way I got around this is by using mod_rewrite with the [p] option
for a more control. Here is an example..
RewriteRule ^/cob$ http://192.168.1.1/cob/ [R,NC] ## what this does is
add the trailing slash if not there.
RewriteRule ^/cob/(.*) http://192.168.1.1/cob/$1 [P,NC] ## this will
catch /cob/webappage.nsf and anything else after cob
## Then below it will send everything else to your IIS box.
ProxyPass / http://192.168.1.3/
ProxyPassReverse / http://192.168.1.3/
