[jetty-users] Configuring Jetty for FastCGI - and pass env. vars to PHP scripts
Hello and good evening,

on a CentOS Linux server I run 3 instances of Jetty on 3 different IP addresses, serving a servlet and  Wordpress in 3 different languages: English, German, Russian.

The Wordpress installations are configured exactly as described at https://www.eclipse.org/jetty/documentation/current/configuring-fastcgi.html

And the Jetty instances are started by /etc/systemd/system/jetty-en.service (and jetty-de.service at port 8081, jetty-ru.service at 8080):

[Unit]
Description=Jetty

As you can see above I pass some information through the env. variables to the custom Java servlet of my word game.

The above stuff works well, but now I am also trying to pass some configuration information to the few PHP scripts I am also running - and unfortunately this does not work - when I print($_ENV['COUNTRY'); in the PHP scripts, the env. variable is not there.

Is there please a way to pass the env. vars from Jetty process to the PHP scripts run through FastCGI?

The reason why I am asking is that I am trying to reuse as much source code (Java, PHP, _javascript_) while serving my word game in 3 different languages.

Thank you 
Alex

PS: Below is my Jetty config xml file:
