Multi-User Spreadsheet Server

<VirtualHost *:80>
	# The ServerName directive sets the request scheme, hostname and port that
	# the server uses to identify itself. This is used when creating
	# redirection URLs. In the context of virtual hosts, the ServerName
	# specifies what hostname must appear in the request's Host: header to
	# match this virtual host. For the default virtual host (this file) this
	# value is not decisive as it is used as a last resort host regardless.
	# However, you must set it for any further virtual host explicitly.
	#
    # Hint for Apache 2.4
    # You need to enable:
    # - mod_proxy
    # -	mod_proxy_http
    # - mod_proxy_wstunnel
    # else you get a working ethercalc instance with datashifts in it!
