Imagine my webbrowser contacted a server via Bonjour (ZeroConfig). So I know already the IP-Address of the server, but I don't know if port 80 is open. (btw. I don't care if a Firewall is running to block Ping, because in that case there's a reason for it and the server doesn't want to be my friend ;-)).
So I want to distinguish between a state where the server maybe there, but HTTP-services are not. But the *general* question was more towards: - Is there a mechanism in Qooxdoo/Javascript that allows 'Ping'? - Is there some class in the Framework already prepared for polling after the server, or do I have to write my own class' (I guess the latter ;-)) andy On 05.03.09 11:16, "Jean-Baptiste BRIAUD -- Novlog" <[email protected]> wrote: > but what if firewall is configured to give no answer to ping ? > > Could you give us more precisions on the context, why you want to do > that ? > > If it is your network, make sure servers all open port 80 for eg and > HTTP GET is your friend :-) > Beware that will only ensure web server is running.
