Proxy bypass is a means by which Internet users can browse websites that might otherwise be blocked by a network administrator. However, the term is a misnomer because it is the use of a proxy that provides its own circumvention of existing blocking mechanisms. So, in essence, a user is not bypassing a proxy to the extent that they are using it to bypass another means by which access to a specific website or service is denied. In many cases, these blocking methods are more of a proxy server or service.
Proxy bypass is a means by which Internet users can browse websites that might otherwise be blocked by a network administrator.
The use of a proxy came into play for several reasons. Most of them revolve around caching web content for faster client access behind a proxy, providing user anonymity, or other security purposes such as encryption, virus scanning, and data integrity. data. Another type is used to monitor Internet content accessed by computers behind a proxy. In most cases, these types of listening proxies are used by commercial networks and educational institutions to deny access to websites that consume precious time.
This latter form of auditing manifested itself in several different ways. There are some websites or entire networks that do not allow access from other Internet Protocol (IP) addresses, essentially blocking access from remote clients originating from a certain region. Contrary to or in addition to external monitoring, network administrators in some large networks implement a proxy server that will monitor requests for content outside the network, which will be configured to prevent access to certain locations on the Internet to improve productivity. or prohibit access to certain types of content. Software programs have also been developed that reside on an individual computer that will block access to certain websites from that computer. Proxy avoidance provides a workaround for these means of access denial.
In most cases, when a service is called proxy avoidance, it is a website that acts as an intermediary, a proxy, to access content that is outside of any acceptable use policy that has been implemented on a network or computer. . Websites that bypass the proxy run Common Gateway Interface (CGI) applications, programmed in various scripting languages, that allow the user to gain access to other websites that would otherwise be blocked. A blocked user loads a proxy prevention website in a web browser and then requests it from the otherwise disallowed web address. Evasion occurs because the system in place to monitor and block access is tricked into thinking the request is coming from or going somewhere else.
Due to the somewhat controversial nature of proxy bypass sites, they are sometimes short-lived or of low quality. If the person creating the website has limited resources, such as network bandwidth or processing power, the website can be overwhelmed by navigation requests and create a miserable user experience while providing access where else mode would not exist. Careful selection of a proxy prevention website is also necessary because it can be used to capture secret information such as passwords or credit card information. Some network administrators also monitor these sites and update their systems to further block access to or from an address known as a proxy prevention site.
