Hello there,
I have a remote site containing lots of Windows Clients, which have no access to WSUS server but nginx.
What I want to achieve is ; get the WSUS updates over the nginx proxy saving bandwith for me.
I checked this URL http://wiki.nginx.org/WSUSProxy and made the proxy work. I am testing with a client and can see that nginx is proxy'ing the file for the client.
But it is not caching. Everytime I start a new download for a specific cab file, nginx downloads from the cab file from the WSUS server again. (checking with netstat) The /cache/wsus is empty, there is no error. Eventhough there is no /cache directory nginx is not complaining about that. How can I open full debug logging ( HIT MISS stuff)? I am not familiar with the syntax.
How can I validate if the static caching is going to work? I am testing with 1 test client but I can not test it with all clients ( over 800)
OS:Centos 5.7 i386
nginx version: nginx/1.0.11
conf file is the same as wikipedia ( I am not running any wpad file, clients have proxy set on internet explorer)
There is the logs I get, nginx is putting the some files under the /var/tmp/nginx which is not set anywhere,
also the file is not there after the check..

Should I use a different approach regarding the wiki? ( there is not proxy_cache stuff included on that page, I tried that but could not make it due the lack of experience with syntax)
