best way to refresh a web page

Hello - What's the best way to refresh a web page?
 
I've seen window.location.reload() and window.location.reload(true/false).
 
I think window.location.reload(true/false) indicates whether or not a server-side refresh should be performed.
 
I'm guessing window.location.reload() always does a server-side refresh?  Which technique do you tend to use to reload a web page?
