JJ,

> Oh sorry. Use SessionStorage in that case.

Although I've seen a few mentions of 'Session Storage', it looked like it 
needed quite a bit of scripting to create it (as in, not build-in).  But, 
I'll take another look at it.

The sounds logical enough, and the on tab-closing might even be better than 
keeping it until the browser itself is closed.

I get the "if it doesn't exist" check, but loading it with a timestamp ? 
Not so much.

And thanks.   Knowing what to actually look for makes searching a whole lot 
easier.
