An ASP code that can return to the previous page and automatically refresh the page

  I searched Baidu several times about the return and refresh of the page asp Code （ Or there's that damn “ Do not resend messages , Can't update ” A hint of ！）, Today, I finally got my wish ！ It's really hard to find , It doesn't take much time to come ！

        Its code is ：response.redirect     Request.ServerVariables("HTTP_REFERER") I tried , The result is right . however , I want to show a alert(" Landing successful ！") Dialog box , Then return and refresh , It was found that , Also refreshed , But the dialog box doesn't show ！ Wait and see if there is a better way ！
