ssh over http proxy

For quite some time I've been searching how I could access a ssh/svn through http proxy. I finally found answer for this on lifehacker blogs.

Its pretty simple:
1. Install corkscrew
2. Add this lines to ~/.ssh/config
Host *
ProxyCommand corkscrew http-proxy.example.com 8080 %h %p
# change http-proxy.example.com and 8080 to your proxy server and port


Go through the following URL if you are also want the same
