A proxy server is a web server which can receive and forward requests to another web server. A proxy server can be used as a web filter. All requests made through a proxy server can be filtered based on certain criteria. It can be used to remove malicious scripts and software from getting downloaded unknowingly into the client’s system. A proxy server can track all requests and mask the target server from the client system. As a result, the target server can’t extract the client’s information like ip address, location, etc.
One use of a proxy server is to provide restricted access to wide area network to the client computer systems. An example implementation is in schools and colleges where a proxy server is used as the gateway to the open internet. While accessing the internet through the proxy server, it can check the packets and filter them based on certain rules. It also provides security and more control over the internal network.
Another implementation is in a web proxy where users can browse the web anonymously. Using a free proxy, users can browse anonymously, hide their ip address and private information, bypass network filters, etc. These are also called proxy sites as they are websites which provide proxy services to the user. By using a web proxy, the user is also protected from malicious scripts, trojans, etc. A typical web proxy filters malicious scripts, applications, etc. and forwards safe content to the user.
Such web proxy servers are used by many users for different purposes. And there are numbers of proxy servers which are open for free use by public. But many of these proxies are either blocked or very slow or full of advertisements. It’s hard to find a good proxy which can be used for fast surfing without much trouble. But there are selective free proxies which have very low ads, high speed and fresh. These proxies are available at proxyserverinc.com which is a premium proxy list site for free proxy servers. You can use the proxies available there for free and enjoy the high speed browsing and anonymity. However, use of these web proxies for illegal purposes is strictly against the website terms and are sole responsibility of the user.
