How can I refresh a visualforce page after the save button on the page is clicked? I've tried a few methods, and none have provided the behavior I am looking for.

1. window.location.reload()

2. window.location.reload(true)

3. Returning the page's url from a function.

    public pagerefrence methodname(){
        PageReference pr = new PageReference('/apex/VFPage');
        pr.setRedirect(true);
    }
