I am running a nginx web server. with this following config return 302 https://www.mysite.com/game_errorpage.php?sub=$name; The intent, is if someone types in "blah.mysite.com" and that subdomain (game server) is not running, I want them to be redirected to a error page. This error page then starts the game game server in question. This all works up to to this point. Then I want to redirect the user back to the original request url, to log into their game "blah.mysite.com" I use the following php header("Location: https://blah.mysite.com"); exit(); The issue I have is, because the browser has it cached already as https://www.mysite.com/game_errorpage.php?sub=$name it keeps returning there even though the game server is now running. The only thing I can do is close all the browsers and open a new window in Chrome using "Incognito" then type the url again. I have the following in my global file, for all pages. header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); So I am looking for some creative solutions. Thanks. Brad
