  The certificate used on this example has been generated for a host named stark.
  So as host we SHOULD use stark if we want the server to be authorized.
  For testing this we should add on the computer running this example a line on
  the hosts file:
  	/etc/hosts [UNIX]
  		OR
  	\System32\drivers\etc\hosts [Windows]
  
  The line to add on the file should be as follows:
  	<the ip address of the server>	stark
