Performs a hard reload of the document associated with the location object. This kind of reload resets form elements to their default values (for a soft reload, use history.go(0)). By default, the reload( ) method performs a conditional-get action, which retrieves the file from the browser cache if the file is still in the cache (and the cache is turned on). To force a reload from the server, force an unconditional-get by adding the true Boolean parameter.
