I have 5 instances of a FCGI application. My config is like this:

upstream servercom {  
server 127.0.0.1:44440;  
server 127.0.0.1:44441;  
server 127.0.0.1:44442;  
server 127.0.0.1:44443;  
server 127.0.0.1:44444;  
}

location ~ .app$ {  
fastcgi\_pass servercom;  
fastcgi\_index stream.app;  
fastcgi\_param SCRIPT\_FILENAME  
/var/www/htdocs$fastcgi\_script\_name;  
include /etc/nginx/fastcgi.conf;  
}

The FCGI application uses X-Accel-Redirect to return a .flv video. The  
problem is that it only works for 1 file. After that, nginx always  
throws 404.

If I don’t use upstream servercom and have fastcgi\_pass like so:  
location ~ .app$ {  
fastcgi\_pass 127.0.0.1:44440;  
fastcgi\_index stream.app;  
fastcgi\_param SCRIPT\_FILENAME  
/var/www/htdocs$fastcgi\_script\_name;  
include /etc/nginx/fastcgi.conf;  
}

It will work fine and always return the file that the FCGI application  
sent by X-Accel-Redirect

Well the thing is that requests that return HTML always succeed, only  
X-Accel-Redirect responses fail with upstream.

Also the application always receives the request and sends it’s  
response successfully.
