I'm looking for some kind of HTTP Tunnel implementation for my own VPSes similar to Ultrasurf. Ultrasurf is the only bypass I can use on my restrictive network but I don't like how everything passes through their servers. Everything other than HTTP and HTTPS traffic (pretty sure they can tell which kind of traffic it is, not just port outgoing) is blocked, except for tunneling through the corporate proxy.
VPNs, SSH Tunneling and Proxies don't work.
I'm curious if there are any solutions I haven't heard of yet to implement something along the lines of Ultrasurf, which apparently uses Squid HTTPS tunneling, but I'm not totally sure how that works myself.
