List and describe two advantages of a proxy server.

What will be an ideal response?

Increased speed - because proxy servers can cache material, a request can be served from the cache instead of retrieving the Web page through the Internet. Reduced costs - a proxy server can reduce the amount of bandwidth usage because of the cache. Improved management - a proxy server can block specific Web pages and/or entire Web sites. Some proxy servers can block entire categories of Web sites such as entertainment, pornography, or gaming sites. Stronger security - acting as the intermediary, a proxy server can protect clients from malware by intercepting it before it reaches the client. In addition, a proxy server can hide the IP address of client systems inside the secure network. Only the proxy server's IP address is used on the open Internet.
