Rescanning the device for size maps :

General idea of the config
https + proxy pass + virtual host
Nginx as a proxy causes a failure of wss:// connections to the backend server.

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection “upgrade”;
proxy_set_header Host $host;
Voila’ !!!

Hi,
Ubuntu does not carry chkconfig any more ..
besides the standard
update-rc.d apache2 defaults
or
update-rc.d apache2 remove
There is a cool tool called : sysv-rc-conf.
This tool can be installed using :
