Subject: RE: [users@httpd] ProxyPass issues

Looks to me like it's an issue with the backend server not Apache. Have you
validated that the IIS server is responding to requests within the timeout
period when the problem is manifesting itself? A simple test would be to use
wget from the Linux host to the IIS server when you see the problem. 


Cheers,

Jeff
