Getting unstuck on an HTTP island...

Sometimes while traveling, you come across a hotel network or a Wifi spot that has a restrictive firewall that only allows HTTP traffic to flow through. What if you wanted to check company email through IMAP/POP3 service? Are you stuck on an HTTP island? Well, no. Luckily there is a workaround.

httptunnel (written by Lars Brinkhoff, license: GPL) creates a bi-directional virtual data connection, tunneled in HTTP requests. So basically, you could connect to any service you wanted, through this HTTP tunnel. The traffic flows right through the network's firewall unobtrusively, because its all HTTP traffic after all.

Have fun!
