Proxy Server Definition

On some networks, the only way to browse the Internet is through a proxy server. For web users, a proxy server can be used to reach blocked websites. Because of these reasons, proxy servers are popular with users.

  1. Definition

    • A proxy server acts as an intermediary between websites and web browsers. Web browsers are configured to use a proxy server instead of accessing websites directly on the internet.

    Performance

    • A proxy server caches frequently accessed data. If a web browser requests cached data, the proxy server can retrieve it quickly instead of making another request across the Internet, which is slower.

    Getting Through

    • A network can be configured so that the only way to reach the Internet is through a proxy server that allows only authorized users who have an account.

    Restrictions

    • Local network policies can be enforced by proxy servers. For example, proxy servers can be configured to deny access to social networking websites.

    Getting Around

    • Web users can reach blocked websites by using a public proxy server on the Internet that is not being blocked.
