- Provide your web site at https, if that was not the case.
- Build your website in such a way, that important functions are running on the https. This means, when someone blocked the port 443 it has no longer make sense to work. This can be for example the login like in Ebay, the query function like in Google or the search and purchase like in Amazon.
- Set up a TOR client.
- Configure your https server so that is https://www.yourbuisness.com/http://www.sometarget.com the content of http://www.sometarget.com from the Tor network.
From the point of view of a dictator this is no longer distinguishable from one access to the website https://www.yourbuisness.com. Because of the usage of the TOR network any attempt to punish access of prohibited websites is impossible. Only if something is prohibited in any country where TOR servers are on the track, you can follow the trace of the user. Correlation analysis can not work! The Dictator only has the choice to block access to https://www.yourbuisness.com. or to endure the hole. If enough big Websites do this by her own decision or president Obama creates a law to do this on big websites, and censorship will wipe out in Iran, China and everywhere where Internet exists!
The only remaining method of censorship would be the type of Dictators Pol Pot and Kim Jong-Ils. Only the economic disadvantages are so huge that on a permanent basis will not work, because in the future, the support for each product will come over the Internet.
