First created in 1996, CGIProxy is a clientless web proxy that supports Javascript and Flash, enabling access even to the most complex websites, and can be used to anonymize connections and circumvent censorship. Over the years, CGIProxy has been downloaded over 2 million times and has been a model for several other similar web proxies.
Actively maintained and developed, CGIProxy is installed in numerous servers, allowing for a decentralization that makes these web proxies harder to block and, if the server is hardened, to detect. Users just need to access the proxy interface of a trusted server through a common web browser and to enter the URL of the website they want to visit in the form. Without having to install anything in their computers, anyone can thus securely and anonymously access any restricted website.
