Does anyone have any suggestions for a proxy server/appliance? What I have is a group of machines which we have restricted to being able to access local resources only. The problem is that there are three external webs sites that we need to be able to access. I am not able to whitelist just those sites with the method we currently have deployed but I could use a proxy server. Hence my question. The only thing I need the proxy to do is allow access to the three desired sites, caching and authentication is not required. I have tested it with our primary proxy server so I know it will work, but I don't have access to or control over the existing proxy so I would have to configure my own. Any help or suggestions greatly appreciated.
