Content filtering proxy servers will often support user authentication to control web access. It also usually produces logs, either to give detailed information about the URLs accessed by specific users or to monitor bandwidth usage statistics. It may also communicate to daemon-based and/or ICAP-based antivirus software to provide security against viruses and other malware by scanning incoming content in real-time before it enters the network. In practice, proxy servers often also perform a logging function to register activities within a network. Many Internet users also use proxy servers to anonymize their own IP addresses. The use of dedicated proxies on the Internet reduces the server load and makes data packets easily available.

What Is HTTP Proxy?
This can cause problems where an intercepting proxy requires authentication, and then the user connects to a site that also requires authentication. Intercepting proxies are also commonly used by ISPs in some countries to save upstream bandwidth and improve customer response times by caching. This is more common in countries where bandwidth is more limited (e.g. island nations) or must be paid for. Intercepting proxies are commonly used in businesses to enforce acceptable use policies and to ease administrative overheads since no client browser configuration is required.
A proxy server will recognize these as your favorites and make your access to them more reliable. When browsing the web, your access to certain websites might be denied due to your IP address or location restrictions. In this case, a proxy will act as a bridge and mask your true address, making your target website recognize its address as your own. When voting by proxy remotely, shareholders may be eligible to vote by mail, phone, or internet.
How does a Proxy Server Work by Using the Example of a Website Call?
Reverse proxies are a strong option for popular websites that need to balance the load of many incoming requests. They can help an organization reduce bandwidth load because they act like another web server managing incoming requests. The downside is reverse proxies can potentially expose the HTTP server architecture if an attacker is able to penetrate it. This means network administrators may have to beef up or reposition their firewall if they are using a reverse proxy. A anonymous proxy is best suited for users who want to have full anonymity while accessing the internet. While anonymous proxies provide some of the best identity protection possible, they are not without drawbacks.
There are various ways of communicating between an internal network and the Internet via a proxy server. In many installations, the IP address of the proxy server is configured manually on the client or declared as an environment variable. In this the client requests its internal network server to forward to the internet. Since the proxy server hides the identity of the user hence it protects from spam and the hacker attacks. However, this article only touches upon the importance and benefits of having a proxy server.
