HTTP status code bug?

Hello,

The browser hits a non-existing file. An “error_page” points
to a fastcgi-application. The fastcgi thinks this is not an error
and explicit sets: “Status: 200” or “Status: 302”, …

One would expect that the fastcgi can overwrite the status-code.

E.g.: http://www.domain.name/media/id12345
nginx returns 404, regardless of the fastcgi.

http {
server {
listen 80;
server_name www.domain.name;
error_page 404 /index.cgi;
location / {
index index.cgi;
fastcgi_pass unix:/var/run/fastcgi/dispatch.sock;
…;
}
location ^~ /media/ {
alias /var/www/media/;
}
}
}

Thanks
Marcus

Normally error pages are mapped to static files, and their status
is obviously 200. It would be a bit strange to return status 200
just because error page was found, right?

If you want to override original error code with one returned by
error page itself, you should use ‘=’ in error_page directive.
See here for more details:

http://wiki.nginx.org/NginxHttpCoreModule#error_page

E.g.: http://www.domain.name/media/id12345
nginx returns 404, regardless of the fastcgi.

http {
server {
listen 80;
server_name www.domain.name;
error_page 404 /index.cgi;

  •     error_page      404 /index.cgi;
    
  •     error_page      404 = /index.cgi;
    
    location / {
        index           index.cgi;                   
        fastcgi_pass    unix:/var/run/fastcgi/dispatch.sock;
        ....;        
    }                                                          
    location ^~ /media/ {                              
        alias /var/www/media/;            
    }                                                          
}
