We currently use WinGate but we've run out of licenses as well as having let the support agreement lapse (mainly because QBIK don't seem very interested in updating it). It doesn't make a lot of sense for us to re-purchase Wingate with more licenses as we only use a very small part of the overall package - the proxy server service.
Therefore we're in the market for a replacement. Anyone hazard to list the top five proxy server applications or know of a website that reviews/discusses proxy servers?
We're aware of Squid which on paper looks perfect but I'd like to at least have a look at the other options.
BTW - the only primary reason we use a proxy server, as opposed to letting everyone out through the firewall, is because we use Citrix XenApp and using a proxy server is a way of allowing us to direct web traffic out via a different internet connection (gateway) than the one used for XenApp traffic itself. XenApp works well with low bandwidth but remote users really do notice latency. Therefore, keeping web browsing/download traffic off the link really helps with the user experience. I've always wondered that whilst proxy server solution works okay, there might be another way to achieve this, e.g. some software that directs XenApp traffic down one route but all other traffic (mainly HTTP port 80) down another gateway.
