A U.S. proxy server is needed when a person requires an intermediary between her web browser and the Internet. These servers can be used for several processes, including improving browsing performance, increasing security or filtering out content.
A U.S. proxy server can be used to improve performance, filter content, encrypt data or get through filters. They are also commonly used for translation and security. One of the most common types of proxy servers used is the Web proxy server. Many of these servers can be found online and used for free.
By use of a proxy server, important information can be prevented from reaching the Internet. For example, a person's external IP address becomes accessible when she is online, but through a proxy server, the IP address can be replaced for security purposes. A proxy server can also accept all the cookies in place of a computer and even block them completely.
Additional features of a proxy server include removing ads from websites, blocking malicious web pages that can harm a computer and caching files to reduce page load times. In general, a U.S. proxy server can be used whenever a person wants to have more control over her online experience and security.
