  • A Proxy Server is an intermediary machine between client and the actual server which is used to filter or cache requests made by the client.. And a web server is a program that uses HTTP protocol to serve the files that form web pages to users..
  • Most routers provide functions including proxy services, which allow some controls over access to servers within your network, For instance, port forwarding and DMZ can direct incoming traffic through the proxy to go to specific servers on your network; web/http (port 80) could be directed to one server and file transfer/ftp (port 21) to another. Some proxies (usually software based) allow finer control, such as using the origination ip address and passwords to identify the user and have even finer control of which server to direct the requests.
