/* <!-- in case someone opens this in a browser... --> <pre> */
/*
* This is a simple multi-threaded Java proxy server
* for HTTP requests (HTTPS doesn't seem to work, because
* the CONNECT requests aren't always handled properly).
* I implemented the class as a thread so you can call it
* from other programs and kill it, if necessary (by using
* the closeSocket() method).
*
* We'll call this the 1.1 version of this class. All I
* changed was to separate the HTTP header elements with
* \r\n instead of just \n, to comply with the official
* HTTP specification.
*
* This can be used either as a direct proxy to other
* servers, or as a forwarding proxy to another proxy
* server. This makes it useful if you want to monitor
* traffic going to and from a proxy server (for example,
* you can run this on your local machine and set the
* fwdServer and fwdPort to a real proxy server, and then
* tell your browser to use "localhost" as the proxy, and
* you can watch the browser traffic going in and out).
*
* One limitation of this implementation is that it doesn't
* close the ProxyThread socket if the client disconnects
* or the server never responds, so you could end up with
* a bunch of loose threads running amuck and waiting for
* connections. As a band-aid, you can set the server socket
* to timeout after a certain amount of time (use the
* setTimeout() method in the ProxyThread class), although
* this can cause false timeouts if a remote server is simply
* slow to respond.
*
* Another thing is that it doesn't limit the number of
* socket threads it will create, so if you use this on a
* really busy machine that processed a bunch of requests,
* you may have problems. You should use thread pools if
* you're going to try something like this in a "real"
* application.
*
* Note that if you're using the "main" method to run this
* by itself and you don't need the debug output, it will
* run a bit faster if you pipe the std output to 'nul'.
*
* You may use this code as you wish, just don't pretend
* that you wrote it yourself, and don't hold me liable for
* anything that it does or doesn't do. If you're feeling
* especially honest, please include a link to nsftools.com
* along with the code. Thanks, and good luck.
*
