Reload method , which forces the browser to refresh the current page.
Syntax: Location.reload ([Bforceget])                                                                                                                                   parameters: bforceget, optional parameter, default is False, the current page is taken from the client cache. True, the latest page from the server is taken as a GET, which is equivalent to the client clicking F5 ("Refresh")

The Replace method , which replaces the currently cached item in history (client) by specifying a URL, so you cannot access the URL that has been replaced by "forward" and "back" after using the Replace method.
Syntax: Location.replace (URL)

In the actual application, when re-refresh the page, we usually use: Location.reload () or history.go (0) to do. Because this practice is like the client point F5 Refresh the page, so the page method= "POST", there will be "page expiration" prompt. That's because of the session's security protection mechanism. It can be thought that when the Location.reload () method is called, the ASPX page is already present in the server memory, so it must be IsPostback. If there is such an application: we need to reload the page, which means we expect the page to be re-created on the server and we expect it to be not IsPostback. Here, Location.replace () can complete this task. The Replace page is regenerated on the server each time.

You can write this: Location.replace (LOCATION.HREF);

To return and refresh the page:

Location.replace (Document.referrer);
Document.referrer//URL of previous page

Do not use History.go (-1), or history.back (), to go back and refresh the page, neither of these methods refreshes the page.
