+The application could be quite easily made to use FastCGI. Unlike normal CGI,
+with FastCGI (fcgi), the process is executed once, and continues to run. The
+process will receive responses from the browser in the response loop. Hence,
+sensor data can be read in another thread while the response loop runs.
+
+Setup:
+Compile fastcgi_test.c with:
+gcc fastcgi_test.c -lfcgi -o fastcgi_test
+
+Configure nginx to pass all requests to the address /cgi/ to the application:
+Edit /etc/nginx/sites-enabled/default by adding the contents of nginx_server_config.txt
+
+Restart nginx:
+/etc/init.d/nginx restart
+
+Run the application:
+spawn-fcgi -p9005 -n ./fastcgi_test
+
+You can see the results at:
+http://your.domain/cgi
