try_files and $fastcgi_path_info

[https://stackoverflow.com/users/573152/bernard-rosset]

Using the following configuration:

fastcgi_split_path_info ^(.+\.php)(/.*)$;
try_files $fastcgi_script_name =404;
fastcgi_pass   php:9000;
fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
include        fastcgi_params;

with the following URI:
​http://nginx/php.php/foo/bar

the following PHP $_SERVER variables are not set properly:

• DOCUMENT_URI set to /php.php instead of /php.php/foo/bar
• PATH_INFO set to empty instead of /foo/bar
• PHP_SELF set to /php.php instead of /php.php/foo/bar

Removal of the try_files directive produces the expected variables assignement.

Note that the values being checked by try_files have no impact on the bug, ie using the following directive configuration

try_files $uri =404;

also triggers it

Mistake:
In the last note, if you use

try_files $uri =404;

with request URI ​http://nginx/php.php/foo/bar, you will most probably end up with a 404.
Rather use

try_files /php.php =404;

to test the non-dependency of the bug on try_files value
