 ###features
 
 - reverse-proxies incoming http.Server requests
+- can be used as a CommonJS module in node.js
 - can handled malformed http requests
 - uses event buffering to support application latency in proxied requests
 - minimal request overhead and latency
 - fully-tested
 - battled-hardened through production usage @ nodejitsu.com
-
+- written entirely in javascript
+- easy to use api
 
 ###when to use node-http-proxy
 
 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.
