I use host that has custom ErrorDocument settings already set in their httpd.conf and I can't edit this file (I don't have access) to solve the problem directly there.
Some background: I use an API that when something isn't right I manually set a responde code and print a json as error response to use in client side. Since I am triggering a response code (400 - Bad Request in my case) it falls directly in the catch of my Ajax request.
Their configuration for a custom 400 error page is causing this issue, the response of my API never returns because i got as response their custom page.
Is it possible to remove/reset or set it to show the page that triggered the error of an already set ErrorDocument via .htaccess?
On server where virtual server settings cannot be modified but .htaccess is accessible, this works for me:
ErrorDocument 401 default
ErrorDocument 402 default
ErrorDocument 403 default
ErrorDocument 404 default
ErrorDocument 500 default
ErrorDocument 501 default
ErrorDocument 502 default
ErrorDocument 503 default
ErrorDocument 504 default
Put it into .htaccess and it will reset error handling pages.
