upstream_phpcgi_unix.conf

### Upstream configuration for PHP FastCGI (PHP-FPM).

### ***IMPORTANT NOTE:***
### This configuration uses three pools for PHP5-FPM
### named www1, www2 and www3.  It is not necessary 
### that you use this configuration for PHP5-FPM 
### but you **must** make sure that the configuration 
### here matches your PHP5-FPM, either by changing 
### this configuration or your PHP5-FPM configuration.
