1) With your script all seems to work fine, but after a while my web application has been in idle, PHP-FPM somehow shuts down and I have to start it manually for PHP pages to work again, otherwise all what I get is “502/bad gateway” with Nginx.
Any suggestions?

2) I found another script, which I paste below, from http://www.johnyerhot.com/2008/02/12/how-to-nginx-fcgi-php-mysql-ruby-on-rails-rewrite-vhosts/.
If I use this script it works the same, but I read fastcgi in there while in your script I read cgi. What is the actual difference?

Thanks!
