So I'm trying to see if I can set reponse headers by configuring them in Apache.
I'm using Debian testing, in case that matters.
My web server is working and I've been using it for multiple websites that I'm developing. So now all I want to do is set a header to see if it works.
This is what I changed in my apache.conf
<Directory /home/web>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
Header set myHeader "Hello Header World"
</Directory>
This is what I host configuration file in /etc/apache2/sites-available/000-default.conf looks like:
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /home/web
AliasMatch ^/vmapi/(.*)$ /home/web/vmapi/api_receiver.php
AliasMatch ^/inherentvalue/api/(.*)$ /home/web/inherentvalue/api/api.php
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
Header set location "juancito"
Header set Location "pedrito"
Header set MyHeader "Hello Joe. It took %D microseconds for Apache to serve this request."
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet
The alias is there for another project, I'm working on.
Also the output of apache2ctl -M looks like this:

So then I try the following command:
curl -i -s -k -v -X GET "http://localhost/vmportal/css"
And the result is this:
HTTP/1.1 301 Moved Permanently
Date: Wed, 24 Nov 2021 06:32:01 GMT

</body></html>
Shouldn't I be seeing ANY of the headers that I set in the response?
Can anyone tell me what I might be doing wrong? Or what the problem could be? Or even how to debug it? (There is nothing in the error logs or the access logs, in case you are wondering).
