Issue "FPM application served by nginx" results in empty PATH_INFO

[lukas_we]

Hello,

I have a server using the "FPM application served by nginx" option, but this results in an empty $_SERVER['PATH_INFO'] variable. The bug comes from the file located at the following position on my server:
/opt/psa/admin/conf/templates/default/domain/service/fpm.php

In that file, fastcgi_split_path_info is used set the $fastcgi_path_info variable, which is subsequently used to pass the path info to the fpm application via:

fastcgi_param PATH_INFO $fastcgi_path_info

However, between invoking fastcgi_split_path_info and fastcgi_param, try_files is called. This sets $fastcgi_path_info to an empty string (see #321 (try_files & $fastcgi_path_info) – nginx) with the effect, that the real path info never gets passed to the fpm application.

The following patch fixes the problem:

-        fastcgi_param PATH_INFO $fastcgi_path_info;
+        fastcgi_param PATH_INFO $path_info;
         fastcgi_pass "<?php echo $VAR->domain->physicalHosting->fpmSocket ?>";
         include /etc/nginx/fastcgi.conf;

Best regards,
