I have a website that displays a warning after 15 mins of no activity. If the user clicks OK it will reset the timer. This is all on the client side of course. When the user clicks OK I'd like to send something to the server to make the session current. This is all being done in javascript btw. My question is, what built in functions does javascript have that does this. I have found stuff like request, doget, doheader, etc. but I never found any syntax for it and don't really know if it should be used in this purpose. TIA
