Question about php-fpm and fcgi multiplex connections

[Alex <al-php@xxxxxxx>]

Hi.

Is it possible to use multiplexing feature for php-fpm?

There is a "FCGI_CANT_MPX_CONN" which implies to me that php-fpm can't used 
multiplexed connections but I'm not sure.

https://github.com/php/php-src/blob/master/main/fastcgi.h#L71

Best regards
