Control Apache’s public server information

By default Apache displays information about itself in the server signature included with reply headers and sometimes auto-generated pages. This information can give away important clues, like the exact version number of a module or Apache itself.

You sometimes need to password protect a folder or an entire account/website from direct access. That’s easily done with the appropriate .htaccess file in the protected folder plus the mandatory .htpasswd file with the correct user and password combination(s).
