Reopening due to attached network trace.
Notes:
- 192.168.0.1 is the gateway (I'm guessing a WLAN router)
- 192.168.0.2 is a Windows XP box connected via WLAN
- Dump was taken on the XP box using netcap (appearantly comes with XP)
  first netcap was started, then FiBs and a connection was attempted by clicking
  on Game->Play Online
FiBs calls InternetCheckConnection with
lpszUrl="http://www.fibs.com/savedgames/list.html"

As one can clearly see from the dump, Windows indeed opens a TCP connection to
the specified machine, on a port given by the URL, then closes it again.

Mike: I have grepped the whole 0.9.19 source, and there is no function called
'InternetOpenConnection'.

saulius: Could you please post the MSDN URLs to which you refer?

Juan: Wether or not the function is reliable is irrelevant.
