Вопрос
I have a custom FastCGI application behind Nginx and I'm struggling to get Nginx to return anything other than a 200 status code.
I've tried the following:
Setting fast_cgi_intercept_errors on.
Returning codes via ApplicationStatus in the EndRequest.
Returning Errors on the StdError stream.
Sending any of following headers:
"Status: 404 Not Found"
"HTTP/1.1 404 Not Found"
"X-PHP-Response-Code: 404"
"Status: 404 Not Found;"
"HTTP/1.1 404 Not Found;"
"X-PHP-Response-Code: 404;"
Any help would be great, I'm very stuck.

nginx discards the "HTTP/1.1 304 Not Modified\r\n".
nginx uses (and eats) the Status header.
If my fastcgi program returns the header "Status: 304\r\n".
Then I get this response:

RussianHTTP/1.1 304
Server: nginx/1.6.2

As you can see there is no Status: 304 header. It has been eaten by nginx.

Here is an example of how you can return a 404 status code using fcgi and C++.
#include <iostream>
#include "fcgio.h"
using namespace std;
int main(void)
{
streambuf * cin_streambuf = cin.rdbuf();
streambuf * cout_streambuf = cout.rdbuf();
streambuf * cerr_streambuf = cerr.rdbuf();
FCGX_Request request;
FCGX_Init();
FCGX_InitRequest(&request, 0, 0);
while (FCGX_Accept_r(&request) == 0)
{
fcgi_streambuf cin_fcgi_streambuf(request.in);
fcgi_streambuf cout_fcgi_streambuf(request.out);
fcgi_streambuf cerr_fcgi_streambuf(request.err);
cin.rdbuf(&cin_fcgi_streambuf);
cout.rdbuf(&cout_fcgi_streambuf);
cerr.rdbuf(&cerr_fcgi_streambuf);
cout << "Status: 404\r\n"
<< "Content-type: text/html\r\n"
<< "\r\n"
<< "<html><body>Not Found</body></html>\n";
}
cin.rdbuf(cin_streambuf);
cout.rdbuf(cout_streambuf);
cerr.rdbuf(cerr_streambuf);
return 0;
}
