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
