"Ever come to work and realize you left a required file at home? Or you’re out on the road and find yourself in the same situation? Some environments and ISPs have strict firewall rules that can make life difficult. In some cases, these rules are absolutely required, in others perhaps not so much. If you are in an environment that disallows the use of SSH and forces the use of an HTTP proxy, it is possible to use that HTTP proxy as a transport for SSH.

"Please note that I am not advocating breaking out of your environment’s firewall if you have a policy that expressly prevents that or outbound SSH access! Unfortunately in the real world, some draconian firewall rules are in place that cause more grief than they need to and without a real reason. In some environments, however, the explicit denial of outbound SSH is required and for that reason you should respect the policy. I am not at all advocating breaking any rules unless you have permission or an exception from the people that should provide it."
