A proxy server is a dedicated server that acts as an intermediary between the server providing the service and the client that requests it. The client does not need to communicate directly with the configured proxy server over the Internet, which improves security. It should be noted that if you are interested in high-quality proxies, then you need to visit the site – You-Proxy.
In addition, a proxy server can help reduce Internet bandwidth usage through its caching capability. For these reasons, a proxy server is usually deployed on a corporate network as a standard feature.
A Windows computer can be configured to use an explicit proxy, and an administrator can also configure proxy settings using Group Policy Preferences to maintain configuration consistency across the domain.
When using a proxy server, every time a client requests some web content from the Internet, it actually sends a request to the proxy server. The proxy will then download the requested content from the Internet and transmit it to the client.
In this scenario, the network topology is shown below. The domain controller is installed on Windows Server 2012 R2 and Group Policy will pass the required proxy address so that the client can safely and efficiently browse the Internet using Internet Explorer or another browser.
In the Group Policy Management Console, open any existing policy, or create a new one, and then open one of the following destinations:
· User Configuration> Preferences> Windows Settings> Registry = To apply a user-level setting, this setting will follow the user on every computer he is logged on to.
· Computer Configuration> Settings> Windows Settings> Registry = To apply the setting at the computer level, this setting will be applied to the computer for all users who are logged on.
The nice thing about configuring a proxy using Group Policy settings is that clients can still manually change the settings when needed. This is useful if clients frequently connect to the Internet outside the domain, where the configured proxy setting might not be appropriate, or when a site needs to be quickly added to the exclusion list. When the client reconnects to the domain, the settings will revert to the values set in the GPO.
But for what specific purpose and in general why use personal proxies?
First, they help maintain privacy so that different sites cannot know which user is visiting them.
Secondly, it is very important to increase your level of the security in the world wide web, because every common request will be aimed by the administration at proxies. But if you are going to use only paid proxies, then such proxies have a really good quality of protection to its user.
Thirdly, in addition, a personal proxy is required in order to be able to access information data that exist only in a specific location.
Fourthly, it is also required in order to speed up access to some of the resources on the Internet.
And finally, fifthly, a proxy is also important in order to be able to access blocked sites and various messengers.
