Mod_rewrite in 2.4.25 FCGI launch "Primary script unknown" error in php-fpm 5.6.30

• Apache: 2.4.25 (localhost)
• PHP-FPM: 5.6.30

This script does not work under Apache 2.4.25, but it does work under Apache 2.4.20.

Test URL:

https://server/some-app/fun

And the contents of the directory:

drwxr-xr-x 118 xx root 4012 May 18 16:12 ..
-rw-r--r--   1 xx root  155 May 18 16:15 index.php
-rwxr-xr-x   1 xx root  450 May 18 16:25 .htaccess
drwxr-xr-x   4 xx root  136 May 18 16:25 .

      

        
        
        
      

    

I expect index.php to be served and "/ fun" will be passed as a GET parameter.

.htaccess OK

This version .htaccess

serves index.php without issue, and the GET parameters show "/ fun" as expected:

RewriteEngine on

RewriteCond $1 !^(index.php)
RewriteRule ^(.*)$ index.php?/$1 [L,NS]

      

        
        
        
      

    

index.php is served and $ _GET:

Array
(
    [/fun] => 
)

      

        
        
        
      

    

.htaccess 404

RewriteEngine on

RewriteCond $1 !^(index.php)
RewriteRule ^(.*)$ index.php/$1 [L,NS]

      

        
        
        
      

    

The result is 404, with PHP-FPM giving the error:

[proxy_fcgi:error]  [client 192.168.200.1:59812] AH01071: Got error 'Primary script unknown\n'

      

        
        
        
      

    

Note that the difference is that I removed the question mark from the RewriteRule substitution.

Relevant FCGI configuration:

<IfModule !mod_php5.c>
    <FilesMatch \.php$>
        SetHandler "proxy:unix:///var/run/php-fpm-xyz.sock|fcgi://xyz/"
    </FilesMatch>
</IfModule>

Timeout 3000

DirectoryIndex index.php
