[squid-users] Reverse Proxy of OWA/Exchange 2000

[Eric Kahklen]

I've read through the past posts and haven't been able to pull together 
enought to get my config working.  I am borrowing a config sent to me 
and  trying to get it to work.  Please keep in mind that I haven't set 
the acl's or http_access yet to help eliminate those as problems.  This 
is also in a testing environment so it is not effecting a production 
mail system.  At this point, I get the confirmation of the SSL cert, 
Windows username/password box and enter the test account and password.  
It appears to authenticate to Windows but the screen only shows the 
frames and tries to bring up the OWA page but errors out with Action 
canceled - Internet Explorer was unable to link to the Web page you 
requested.  I am  very  new to Squid, but was told that Squid is the 
ONLY way to user a reverse proxy with OWA/SSL.

I know my squid.conf file is not pretty, but I need to know if I have 
something completely wrong or not.  Some of what is in the original conf 
file I couldn't find documentation on.  I have put all my comments in 
upercase.  I am only looking for help on the OWA issue at this point so 
the ACL stuff doesn't need input at this point unless you have time.  
Any help would be appreciated!!!!

Thanks alot,

Eric
