-Simplistic HTTP proxy support.
-
-This comes in two main variants - the Proxy and the ReverseProxy.
-
-When a Proxy is in use, a browser trying to connect to a server (say,
-www.yahoo.com) will be intercepted by the Proxy, and the proxy will covertly
-connect to the server, and return the result.
-
-When a ReverseProxy is in use, the client connects directly to the ReverseProxy
-(say, www.yahoo.com) which farms off the request to one of a pool of servers,
-and returns the result.
-
-Normally, a Proxy is used on the client end of an Internet connection, while a
-ReverseProxy is used on the server end.
