How to add Apache Headers in Linux 12?

[Delaney martin]

Hi,

I have a problem with Apache2 headers. My needs are to add the HTTP header “X-Served-By” with the server hostname as the value.

Any suggestions?

Hey, this can help.

Check that you have enabled the headers module with sudo a2enmod headers

You can add the header in your site's virtual host config or in the global Apache config (apache2.conf or 000-default.conf):

sudo nano /etc/apache2/sites-available/000-default.conf

Ensure the block <VirtualHost *:80> will look like:

...

SetEnv HOSTNAME ${HOSTNAME}

Header set X-Served-By "%{HOSTNAME}e"

</VirtualHost>

At last, don't forget to restart Apache: sudo systemctl restart apache2

Hi, First, you need to check if the header is present using:

curl -I http://your_server_ip_or_domain

Then you can also set the hostname permanently with this line:

hostnamectl set-hostname your-desired-hostname
