Terminal over http. Wetty is like ajaxterm but much better because it uses ChromeOS' terminal emulator (hterm) which has much better terminal emulation implementation. Also it uses websockets instead of Ajax. Terminal over http.

Note: tested only on Chrome (hterm was written for Chrome.)

Run wetty behind nginx:
----------------------
Put the following config in nginx's conf:
location /wetty {
proxy_pass http://127.0.0.1:3000/wetty;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 43200000;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
}
In the browser you have to use: 'http://yourserver.com/wetty'. Note that if your nginx is configured for https you should run wetty without ssl.
