Include a file globally using the Auto Prepend File field

This guide explains how to specify a file that will be loaded before the desired page, including as if it had been called with the 'require()' function.

For example, to modify the headers of a site, you must make a headers.php (or other) file that contains PHP header() functions and prepended to the beginning of each PHP file:

1. via .user.ini file (specific to a folder)
2. or via the site configuration on the Manager (global)

How to include a file globally

1. open the Manager (manager.infomaniak.com)
2. go to Web hosting
3. click on the hosting/domain name concerned
4. under Sites at the bottom, click on the domain name of the site concerned
5. click on the Advanced settings button
6. in the Apache tab, enter the path of the file to be included
7. save

The headers defined in a .htaccess file are only valid for non-PHP (therefore static) content.

We use php-fpm, which receives the different headers via apache fast_cgi. In the RFC for cgi_www, the "Strict-Transport-Security" header is not among the headers passed via CGI, as confirmed by the Apache document httpd.apache.org/docs/2.2/howto/cgi.html). Also readhttps://www.ietf.org/rfc/rfc3875
