How do reverse proxy servers work?
What will be an ideal response?
When someone on the Internet makes a request to connect to your company's Web server, the request goes first to the reverse proxy server. The proxy server then forwards the request through a specific port to the Web server over the trusted network. The Web server relays the reply back over the trusted, internal network to the reverse proxy server. The proxy, in turn, rebuilds the data packets from scratch (as proxies do) and sends the retrieved information to the client as if the proxy were the actual Web server. If the content server returns an error message, the proxy server can intercept the message and change any URLs listed in the headers before sending the message to the client. This prevents external clients from getting a glimpse of the redirection path of any URLs that point to the internal content server.
