getting data once only

[s_avinash_s]

Hi

I need to get a data only once using 

xhttp.open("GET", "url",true);

But i dont have any button, only when the server and client are running at first, only first it should get a data and later should not.

The client only runs on a event, with button it would be .onclick, a form .onsubmit, with none of these you are left with event .onload which it usually attached to window. that only runs when the document has fully rendered.
