in php, the thing is easy:

if course you could extend this so the currently available version isn't hard-coded inside the script, but this is just about illustrating the point.

In your application you would have this pseudo code:

result = makeHTTPRequest("http://www.example.com/update?version=" + getExeVersion());
if result != "no update" then
    updater = downloadUpdater(result);
    ShellExecute(updater);
    ExitApplication;
end;

Feel free to extend the "protocol" by specifying something the PHP script could return to tell the client whether it's an important, mandatory update or not.

Or you can add some text to display to the user - maybe containing some information about what's changed.

Your possibilities are quite limitless.
