It's run ok on localhost, but when I deploy onto server (free Amazon server), it's often get error 502 Bad Gateway. Now, I also want get Error 502 on my Apache localhost for testing my code. So, how to config server? Thank for helps.

You can use mod_rewrite

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/badurl
RewriteRule .* - [R=502]

All urls, matched pattern "^/badurl" will return 502 error.
