Proxy servers Asia is a computer offering a computer network service to allow users to make indirect network connections to others.
A user connects to the proxy server then requests a connection or other available resource on a different server. The proxy offers the resource either by connecting to the specified server or by serving it from a cache. In some cases, the proxy may alter the the server’s response or user’s request for various goals.
A popular proxy application is a caching Web proxy. This offers a nearby cache of Web pages and available files on remote Web servers, allowing local network users to access them more reliably or quickly.
When it receives a request for a Web resource, a caching proxy will look for the resulting URL in its local cache. If it found, it will return the document immediately. Otherwise it fetches it from the remote dedicated servers in Asia, returns it to the requester and saves a copy in the cache. The cache often uses an expiry algorithm to remove documents from the cache, according to their size, age and access history. 2 simple cache algorithms are Least Frequently Used (LFU) and Least Recently Used (LRU). LRU removes the least-recently used documents, and LFU removes the least-frequently used documents.
Web proxies can filter the data of Web pages served. Some censorware apps – which attempt to block offensive Web content – are implemented as Web proxies. Other web proxies reformat web pages for a specific purpose or client. For example, Skweezer reformats web pages for mobiles and PDAs. Network operators can deploy proxies to intercept other hostile content and computer viruses served from remote Web pages.
A special case of web proxies are “CGI proxies.” These are websites that allow a user to access a website through them. They usually use PHP or CGI to implement the proxying functionality. CGI proxies are often used to gain access to websites blocked by corporate or school proxies. Since they also hide the user’s own IP address from the websites that they access through the proxy, sometimes they are used to gain a degree of anonymity.
You can see references to four different types of proxy servers:
It is known as a proxy server, but makes an incorrect original IP address available through the http headers.
High anonymity Proxy
High anonymity proxy server does not identify itself as a proxy server and doesn’t make available the original IP address.
This type of proxy Asia servers identifies itself as a proxy server, but doesn’t make the original IP address available. It is detectable, but offers reasonable anonymity for most clients.
Transparent proxy identifies itself as a proxy server and makes the original IP address available through the http headers. These are often used for their ability to cache sites and don’t provide any anonymity effectively to those who use them. However, the use of a transparent proxy can get you around simple IP bans. They are transparent in the terms that your IP address is exposed, not transparent in the terms which you don’t know that you are using it.
