feature request: able to play games behind "http proxy"
As a note, in certain locations internet access is accomplished only behind a "draconian proxy" which does allow "CONNECT" functionality, but is basically the only way to get to the Internet. Unfortunately the majority of steam games do not function in such a restricted environment, and multi player is impossible, for instance.

As a note, it seems most games are unable to play if you are required to traverse an HTTP proxy to reach the Internet. Would be nice to fix that.

My apologies if such was asked before. I searched for and saw many threads about "not circumventing policies" by using proxies but this is definitely not that, this is legitimiately using local required proxy servers to access the Internet.

Cheers!

The problem is that games don't use HTTP for their traffic. HTTP is a protocol on top of TCP, which games typically don't use either, they use UDP because TCP implies the introduction of a significant amount of latency in order to provide the guarantees of reliability that TCP provides.

It's also an issue somewhat orthogonal to Steam; most Steam games don't rely on Steam for their network connectivity (apart from those which use the Steam P2P networking API, which is only a fraction of all the games on Steam), so you can't just support HTTP for game traffic in Steam and have it work in most games.

Even if you could get a game to go over port 80/443 most modern firewalls now analyze the traffic and notice that "hey this isn't actually web traffic but some student trying to play CSGO" and will drop the connection anyway.

I assume it would be mostly proxying TCP. Many corporate policies (for instance using SSH) allow you to connect over SSL

Most modern firewalls prevent you from doing that. They analyze your traffic patterns and quickly realize "hey this isn't actually what you claim it is" and drop the connection. Heck most corporate firewalls will decrypt your ssl traffic anyway to see what's inside, then drop it if you're trying to be 'clever' and tunnel CSGO over an SSL tunnel
