Simple HTTP Proxy for fixing server join sessions, skins, and cloaks (capes) in Minecraft Beta versions. There is both a NodeJS script or a nginx vhost that can be used.
To use, simply clone the repository, switch to the node directory, edit the port in proxy.js, and then run npm install and npm start
To use, download the vhost file in the nginx directory of this repository. Upload it to your nginx server, edit the port if you'd like, and restart.
To use on clients and servers, pass the JVM arguments:
-Dhttp.proxyHost={IP}
-Dhttp.proxyPort={PORT}
Replacing {PORT} with the port you set in proxy.js and {IP} with the IP of the proxy.
