Apache not sending headers to PHP over FCGI/PHP-FPM

I have a virtual host configured to process PHP files over Proxy:FCGI, and it works fine, except that PHP is not receiving custom headers and others, like "Origin".

Here my Apache 2.4 virtual host:

<VirtualHost *:80>
    ServerName domain.localhost
    DocumentRoot "/my/host/directory/public"

    DirectoryIndex index.html index.php

    ErrorLog "/my/host/directory/logs/error.log"
    CustomLog "my/host/directory/logs/access.log" common

    SetEnv APPLICATION_ENV local
    Header always set Example01 "*"
    
    <Directory "my/host/directory/public">
        AllowOverride All
        Require all granted
    </Directory>

    <Files ~ "\.php$">
        ProxyFCGIBackendType GENERIC
        SetHandler "proxy:fcgi://127.0.0.1:9000#"
    </Files>
</VirtualHost>

and here, the PHP $_SERVER values returned:

Array

    [USER] => nobody
    [HOME] => /var/empty
    [SCRIPT_NAME] => /index.php
    [REQUEST_URI] => /

)

I was expecting a header named "Example01" and others, but nothing. How can I make it work?

The instruction "CGIPassAuth On" solved my problem. My config changed from

    <Files ~ "\.php$">
        ProxyFCGIBackendType FPM
        SetHandler "proxy:fcgi://127.0.0.1:9002#"
    </Files>
</VirtualHost>

to

    <Files ~ "\.php$">
        CGIPassAuth On
        ProxyFCGIBackendType FPM
        SetHandler "proxy:fcgi://127.0.0.1:9002#"
    </Files>
</VirtualHost>
