If you’d like to know more about HTTP Security Headers and why they are important, make sure that you visit this guide.

Access Your .htaccess File

  1. Log in to your site using SFTP or SSH.
  2. Navigate to your site’s webroot (most typically the /public/ directory).
  3. Open the .htaccess file for editing.

Add the HTTP Security Headers

HTTP Security Headers can be added to your .htaccess file. The .htaccess file is parsed from top to bottom, so order matters. You can add one or more HTTP Security Headers at a time within the <IfModule> directive.

Example: Unset X-Powered-By
This HTTP Security Header removes the X-Powered-By HTTP header, which is often used by web servers to indicate the technology or framework powering the website. Unsetting this header hides server information that can be useful to attackers.

  3. All done!
