Reverse hosting is similar to reverse proxying except that in addition to protecting the servers sitting behind it, it also keeps a list of those servers on the network that are permitted to publish to the Internet. The proxy server listens for requests from those servers and responds for them, thus protecting them from unwanted visitors. The proxy server hides all internal
When configuring reverse hosting, ensure that all incoming Web requests will be discarded by default. This is done through the properties pages of the Web Proxy service under the Publishing tab. Mappings will be added that provide paths to the servers “downstream” or behind the proxy server, and these mappings will connect virtual paths that belong to the proxy server to the actual path of the Web server. Again, for the protection of the internal servers on the network, proxy is the gatekeeper so to speak, inspecting what comes in or goes out, and making sure that its internal network is safe.
