Proxy servers make and handle requests on behalf of clients and servers. In this video, Mike Chapple explains the functioning of forward proxies, reverse proxies, transparent proxies, and multipurpose proxy servers.
- [Instructor] Proxy servers are specialized servers…that browse websites on behalf of end users.…They serve as proxies, or intermediaries, that prevent…users from directly connecting to websites.…Normally, when a user connects to a website,…the user system is in direct contact with the server,…sending information back and forth.…In a proxy situation, the proxy server sits…in the middle of the connection.…The user connects to the proxy server…and the proxy server connects to the web server.…
All traffic then passes through the proxy server.…This has three important security benefits.…First, proxying provides anonymity.…The web server never learns the network address…of the actual user.…Its logs only contain the address of the proxy server.…Second, proxying provides performance benefits…by caching.…The proxy server can store copies…of frequently requested pages and answer some user requests…with those stored or cached copies,…reducing the demand for network bandwidth.…
Finally, proxy servers can perform security tests,…
