Apache Headers could not be set

[Artiom Neganov]

I have Apache 2.2 with libapache2-mod-fastcgi 2.4.7 runing PHP-FPM

The problem is that none of Apache headers which I set via "Header set" directive appear in the output.

I think I tried every possible Header directive option but still no custom headers on the output.

Example things that don't work (they are obvious, but I leave it here for search engines):

* AddDefaultCharset apache directive
* X-Frame-Option
* Access-Control-Allow-Origin
* Content-Type charset

To reproduce, just add to .htaccess a line like:

Header set My-Custom-Header "Some content"

and then try to fetch any file which is processed via mod_fastcgi. For example:

$curl -I http://localhost/index.php

and you will NOT get My-Custom-Header in the output. While this:

$curl -I http://localhost/index.html

perfectly outputs My-Custom-Header.

Any ideas?

Status changed to 'Confirmed' because the bug affects multiple users.

Same behavior here:

Server version: Apache/2.4.18 (Ubuntu)
libapache2-mod-fastcgi Version: 2.4.7~0910052141-1.2

Also
Header always set My-Custom-Header "Some content"

is not working.

Fastcgi is defined like:

FastCgiExternalServer /usr/lib/cgi-bin/php7-fcgi-www -socket /run/php/php7.0-fpm-www.sock -pass-header Authorization
