How do you use jQuery so that it will allow the user to silently load a webpage?

U░ views s░.com
s░.com uses jQuery to silently "view" s▓.com - so that both s░.com and s▓.com will treat U░ as if he viewed both pages.
The process is repeated every 60 seconds.

My goal in this is to use an external software of mine, hosted on a different host, to load a page in my forums so that the forum can do the proper logging procedures... and that I won't need to write up a script to do what my forum does in terms of logging data.
