Proxy servers act as intermediaries between clients (computers or other devices) and the internet, helping to protect a computer network in several ways:n1. Filtering: Proxy servers can filter web traffic based on specific criteria, such as URLs containing certain keywords or content types.n2. Anonymity: By hiding the client's IP address from websites, proxy servers help maintain user anonymity.n3. Load balancing: Proxy servers can distribute network traffic among multiple servers to prevent overloading and improve performance.n4. Content caching: Proxy servers store frequently accessed content on local servers, reducing bandwidth usage and improving access speed.
