Add HTTP Headers in Apache Response

This can be used to for several reasons:

  1. To add headers to modify the behavior of a specific ‘misbehaving’ browser or client.
  2. To replace headers that you don’t want leaked to the Internet.
  3. To add monitoring information to your server responses.

Changes can be accomplished in the Apache2 ‘httpd.conf’ file.

  1. Verify that the module is not disabled or commented out:

    LoadModule headers_module modules/mod_headers.so

  2. To add some common metrics:

    <IfModule headers_module>
    Header append MyHeader “%D %t”
    </IfModule>

  3. To Hide the HTTP Server header that you send in your responses (often done for security through obscurity):
    <IfModule headers_module>
    Header unset Server
    </IfModule>
  4. You could also replace the Server Header like this:

    <IfModule headers_module>
    Header set Server “ScottServer 1.0”
    </IfModule>

Cheers!
