window.open(sURL, sName, [bReplace]);

The bReplace parameter is only supported by Internet Explorer 4 and later. This parameter is useful only when the second argument names an already-existing window. It is a Boolean value that specifies whether the URL specified as the first argument should replace the current entry in the window's browsing history (true) or create a new entry in the window's browsing history (false), which is the default behavior.
