Is seems possible to set environmental variables in a location block which are visible in php.
My external authentication (php) sees these variables:
print_r($_SERVER)
| Quote: |
Array
(
[PATH] => /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
[AUTHTYPE] => PASS
[IP] => 192.168.2.1
[URI] => /Downloads/SecureOffice/r13710/packages_x86_64/Packages.gz
[HTTP_HOST] => redacted.org
[PHP_SELF] => /home/e-smith/files/ibays/rossco/license_server/download_auth.php
[SCRIPT_NAME] => /home/e-smith/files/ibays/rossco/license_server/download_auth.php
[SCRIPT_FILENAME] => /home/e-smith/files/ibays/rossco/license_server/download_auth.php
[PATH_TRANSLATED] => /home/e-smith/files/ibays/rossco/license_server/download_auth.php
[DOCUMENT_ROOT] =>
[REQUEST_TIME_FLOAT] => 1615730112.1554
[REQUEST_TIME] => 1615730112
[argv] => Array
(
[0] => /home/e-smith/files/ibays/rossco/license_server/download_auth.php
)
[argc] => 1
)

In my authentication location block, I have this:
"RequestHeader set HTTP_X_FORWARDED_FOR %{HTTP_X_FORWARDED_FOR}e\n";"
...which does not show up as [HTTP_X_FORWARDED_FOR] in php
Q - how do I get fpm variable HTTP_X_FORWARDED_FOR in my php authenticator? |

In your configuration code:

you are setting a request header based on the current value of an Apache variable, whereas your question is the other way round. You're wishing to set an Apache variable, based on a request header, to be picked up by your PHP code.
So try the following instead:
| Code: | | SetEnvIf HTTP-X-Forwarded-For ^(.+)$ HTTP_X_Forwarded_For=$1 |
Make sure you enable the SetEnvIf module, and note its context is server config, virtual host, directory, and .htaccess - not a location block. I'd put it at the global server level myself. |
