Hi !

The benefit of havong a reverse proxy for exchange ist hat you have just the 
directories published that you really need to have published (/owa, /public, 
/...)and not all directories on the server such as /ews, /ecp, ...

That is the main reason why I made the exchange assistant in the squid 
package...

If you want to cache the files from the backend-servers you might want to 
define some rules with caching enabled ;-)

Regards,

martin

Just out of curiosity, what is the benefit of having a reverse proxy for 
Exchange?  My understanding of a reverse proxy is to provide caching of static 
files, but surely a lot of the traffic on webmail interface is dynamic and/or 
personal to the particular user.  The static parts of the interface would be 
relatively small files, and would quickly be cached at the user client end 
anyway.

We don't use Exchange, but I will be setting up a Horde webmail interface, and 
if there is some benefit to the reverse proxy that I'm missing here, maybe it 
will apply equally to Horde.


As another point, while we're on the topic of reverse proxies, can the reverse 
proxy pass on http requests to different servers based on the web address?  We 
have several (virtual) servers for different uses, with addresses such as 
"svn.westcontrol.no" and "www.westcontrol.no".  At the moment, all incoming 
port 80 traffic goes to a single common apache server, that passes the traffic 
on to the appropriate virtual server. 
If a reverse proxy on pfsense can handle that job, it will cut out an extra 
step.

mvh.,

David
