# The following directives prevent the execution of script files
# in the context of the website.
# They also force the content-type application/octet-stream and
# force browsers to display a download dialog for non-image files.
SetHandler default-handler
ForceType application/octet-stream
Header set Content-Disposition attachment

# The following unsets the forced type and Content-Disposition headers
# for known image files:
<FilesMatch "(?i)\.(gif|jpe?g|png)$">
	ForceType none
	Header unset Content-Disposition
</FilesMatch>

# This is an important complement to the ForceType directive above:
Header set X-Content-Type-Options nosniff

#AuthName "Authorization required"
