Trying to change the "FollowSymlinks" option in a .htaccess file will result in an internal server error, as this option has been disabled for security reasons. Instead, the "SymLinksIfOwnerMatch" option is enabled by default, so you can still use symbolic links to alias your own files. If for any reason you'd like to disable access to symbolic links, just add the following to .htaccess:
Options -SymLinksIfOwnerMatch
You will also receive an error when trying to specify "Options All".
