Anyway, the alternative is called SuperTunnel. There are three main differences between SuperTunnel and HttpTunnel:
- HttpTunnel has a tendency to get packets out of order when processing high-volume traffic. This caused SSH to repeatedly crash when I would use it to forward ports over HttpTunnel. SuperTunnel does not do this; I've verified that it works when both downloading and uploading data as fast as SuperTunnel will send and receive it.
- HttpTunnel only allows one socket connection to be active at a time. SuperTunnel allows up to 200 concurrent connections, and in the future that limit will be specified by a configuration file.
- HttpTunnel uses requests that are long-lived in the sense that a single request will be opened and data streamed down through it as data is received by the server. Since this causes problems with buffering proxies, SuperTunnel instead follows an approach where a single connection will only be used once to receive data. Once even a single byte is received, the connection ends and a new one is made. SuperTunnel waits one second between receive connections so that an excessive number of connections aren't made with each one holding only a couple of bytes.
