It is very common for websites like Bebo, runescape, youtube, xanga, MySpace, Facebook, Miniclip, Richslacker and
many other social websites that are non-school or work related to be blocked. Many schools and companies are
beginning to crack down on these web sites by filtering them and making them inaccessible.
Because of this trend, creators of proxy web servers have come up with more ways to encrypt links, along with the
incoming and outgoing data from the other servers. This lets people go to websites which otherwise would’ve been banned.
CGI proxies are another case of web proxies. They typically do the same job as PHP proxies, as they allow a user
to access any sites through their server. Like the name says, it is generally CGI or PHP that is used when
implementing the proxy functions. These proxies are usually used to get past school or company proxies that filter blocked
web sites and enable the user to gain access. This can also be called Proxy Avoidance, as they also hide IP addresses
from the sites that are accessed through the specified proxy.
