Courtesy of the BBC, here is another report on Internet control in China:
The Chinese authorities have used several methods to “sanitise” what people see online, according to a report from US firm Dynamic Internet Technologies, which watches net use in the country.
On the most basic level, the firewall blocks net addresses hosting webpages that the authorities would rather people did not see. Anyone trying to visit these pages gets told that the page cannot be found or does not exist.
More sophisticated firewall technology spots when people are searching the web for particular words and hijacks their session to stop them getting the information.
