Not sure why but all of my error pages respond with a 200. That's feels a little strange to me, the pages exist but shouldn't they have their corresponding status codes? How do I get Nginx to render my 404 pages with a 404 status code?
For example:
▶ curl -I http://example.com/404
HTTP/1.1 200 OK <<--------------------------- WTF! THIS SHOULD BE 404!!
Server: nginx/1.8.0
Date: Tue, 17 Apr 2018 02:24:04 GMT
Content-Type: text/html; charset=UTF-8
...
Here is the relevant part of my config:
server {
listen 80 default_server;
server_name example.com;
root /var/www/example/static;
index index.html;
try_files $uri $uri/ $uri.html =404;
# error pages
error_page 400 =400 /400; # bad request
error_page 401 =401 /401; # unauthorized
error_page 403 =403 /403; # forbidden
error_page 404 =404 /404; # not found
error_page 408 =408 /408; # timeout
error_page 500 502 503 504 =500 /500; # error
}
In the documentation is states:
... it is possible to change the response code ... using the “=response” syntax
It is true that the page exist but having set an error_page
in the config should change that page's status. For example, if you curl
Google's 404 you get the correct result:
curl -I https://www.google.com/404
HTTP/2 404 <<--------------------------- Ahhh, much better.
content-type: text/html; charset=UTF-8
referrer-policy: no-referrer
content-length: 1564
I need my 404 page to produce a 404 status code since I redirect to it from other parts of my app. This is fine for humans but bad for machines since a redirect produces a 302 followed by a 200 instead of a 404.
