end.Your process should get messages like these:
{fast_cgi_stdout,600,<<"X-Powered-By: PHP/5.6.30\r\nContent-type: text/html; charset=UTF-8\r\n\r\n">>}
{fast_cgi_stdout,600,<<"<html>">>}

{fastcgi_request_done,600,fast_cgi_connection_reset}
There is no pooling support out of the box, but you can use your favorite worker pool library to run as many of these as needed.
