check if online

Hi,

I'm not as close to network, networkprotocolls and co.

question:

Will this be a safe way to check if a user is 'online' (connected to the internet by wlan or lan or ...)

var myConnection = new Socket();
if(myConnection.open ("www.google.de:80")) {myConnection.close();}else{alert('Not connected.')}

sure .. connect to the dropbox URL http://www.dropbox.com oder their API https://api.dropbox.com/ instead of connecting to google

Hi,

your code definitly works
being able to connect to "google.de" is not a save definition of being "online". Firewalls, Proxies etc can ruin your day.
rather check the connection to the online service you want to connect to (if that is google, forget what I said) ..
