[Javascript] Detect internet connection

[Rod Coate]

I think that the question was pointing in the other direction.
I.E. Can you tell if a client machine has a connection to the internet
rather than can someone on the internet tell if a particular client is on.

Not likely in this century.
Since all activity on the internet is IP based, detecting a particular
user's connection is slightly impossible.
You might be able to detect if a particular IP is active, but an individual
user? No way.
That's kind of like trying to find out if so and so is using the phone
without dialing their number.
As the IP is issued by the server, or to it, which ever, it would have to be
static for a particular user.
Even my cable assigned IP changes from time to time.
You can ping the IP to see if it's active, but that's all you'll get.
