Answer 1

My solution is to grab a very small image (1x1), not cached and always onLine.

Notes:

• Use a local copy of jQuery otherwise it won't work offLine.

• I've tested the code onLine/offLine and it works without delay.

• Works with all browsers, Desktop or Mobile.

• In case you wonder, there's no tracking made from Google Analytics as we don't use any arguments.

• Feel free to change the image, just make sure it doesn't get cached and it's small in size.
