Because of Session’s security protection mechanism.

When the location.reload() method is called, the aspx page already exists in the server memory, so it must be IsPostback.
If there is such an application: The page needs to be reloaded, which means that the page is expected to be re-created on the server side, and the expectation is Not IsPostback.
Here, location.replace() can complete this task. The replaced page is regenerated on the server every time.
Code: location.replace(location.href);

Return and refresh the page:
location.replace(document.referrer);
document.referrer //URL of the previous page
Do not use history.go(-1) , or history.back(); to return and refresh the page. These two methods will not refresh the page.
