I have a Fastcgi C++ program as follow:

```auto
1 #include "fcgi_stdio.h"
  2 #include
  3
  4 int main(void)
  5 {
  6 int count = 0;
  7 while(FCGI_Accept() >= 0)
  8 printf("Content-type: text/html\r\n"
  9 "\r\n"
 10 "Tiny3"
 11 "FastCGI World!"
 12 "Request number %d running on host %s\n",
 13 ++count, getenv("SERVER_NAME"));
 14 return 1;
 15 }
```

then i have modified the Nginx conf file

```auto
30 upstream fastcgiends{
31 server 127.0.0.1:9110 weight=1 max_fails=2 fail_timeout=30s;

32 server 127.0.0.1:9111 weight=1 max_fails=2 fail_timeout=30s;

33 }
```

```auto
location =/3.cgi {
             #fastcgi_pass 127.0.0.1:9553;
             fastcgi_pass fastcgiends;
       }
```

start the spawn-fcgi command :

```auto
spawn-fcgi -a 127.0.0.1 -p 9110 -f ./tiny3 -P ./pid/fastcgi_9110.pid
spawn-fcgi -a 127.0.0.1 -p 9111 -f ./tiny3 -P ./pid/fastcgi_9111.pid
```

but I found i can’t query it from the web `
http://122.36.180.89:9095/3.cgi
`

and does anyone konw sth about this problem ?

You should use:  
fastcgi\_param SCRIPT\_FILENAME $document\_root$fastcgi\_script\_name;

Or even better:

`location = /3.cgi {
  fastcgi_pass fastcgiends;
  include fastcgi.conf;
}`
