When one computer wants to use the resources of another computer but cannot access it directly, they may access it through a proxy server. Internet service providers use proxy servers to restrict users from accessing porno and unknown sites. In some countries the government asks the internet service providers to block access to certain sites. As all traffic is routed through proxy servers, the internet service providers are able to block access to their users. Similarly a number of educational institutions restrict the access from their Internets to certain sites.

What a proxy server does is; to keeps the machines access anonymous, which means it hides the machines that are behind it. By using caching it speeds up access to the internet. Popular search engines like Google, msn and yahoo are generally cached on proxy servers. It allows blocking access to restricted sites. Companies use proxy servers to audit access of their employees. A proxy server scans content for malware before delivery. It protects data from leakage. A proxy server can circumvent regional restrictions.

Allowing users to circumvent restrictions and access restricted sites has become the main business of a number of proxy sites. What a user does is that he or she accesses the proxy server and through the proxy server accesses the sites that they want. Like this they don’t leave a trail of the sites that they have accessed through the proxy server. Some of these proxy server sites are free whereas for other you have to pay to use their services.

Proxy servers can be quite useful as they allow user access to all internet sites; therefore a user can bypass local restrictions. Also users know that all content that they send or receive through proxy servers will be scanned and if found dangerous it will be quarantined. This saves the users from getting their computers infected. In case the proxy detects malware on a site it will block it and not allow the user to access it.

You can easily find proxy servers offering proxy services on the internet. You can look at the services that they offer and sign up with any one of them and start using their services. As proxy server service providers are competing with each other, you can get a fairly good deal with a service provider. By using a proxy service provider you don’t have to bother about local restrictions.
