 Let's suppose you were running multiple http application servers, but you only wanted to expose one machine to the internet. You could setup node-http-proxy on that one machine and then reverse-proxy the incoming http requests to locally running services which were not exposed to the outside network.

 A Proxy Table is a simple lookup table that maps incoming requests to proxy target locations. Take a look at an example of the options you need to pass to httpProxy.createServer:

 The above route table will take incoming requests to 'foo.com/baz' and forward them to '127.0.0.1:8001'. Likewise it will take incoming requests to 'foo.com/buz' and forward them to '127.0.0.1:8002'. The routes themselves are later converted to regular expressions to enable more complex matching functionality. We can create a proxy server with these options by using the following code:

 Sometimes in addition to a reverse proxy, you may want your front-facing server to forward traffic to another location. For example, if you wanted to load test your staging environment. This is possible when using node-http-proxy using similar JSON-based configuration to a proxy table:

 If you have a suggestion for a feature currently not supported, feel free to open a [support issue][6]. node-http-proxy is designed to just proxy http requests from one server to another, but we will be soon releasing many other complimentary projects that can be used in conjunction with node-http-proxy.
