# X-Powered-By hidden by default nobody will notice if you're using PHP or whatever
Header unset X-Powered-By
# Set by default UTF-8 charset

Header set X-XSS-Protection "1; mode=block"
# Only allow JavaScript from the same domain to be run.
# Don not allow inline JavaScript to run.
Header set X-Content-Security-Policy "allow 'self';"
# Prevent mime based attacks
Header set X-Content-Type-Options "nosniff"
# Disable server sign
ServerSignature Off
# drop Range header when more than 5 ranges. CVE-2011-3192
