Allows you to control extended HTTP options such as directory browsing and byte range serving.
This option will enable the use of HTTP ranges. HTTP ranges allow for users to request only certain portions of a file from the web server. This allows users to use software that can resume aborted downloads and helps speed up the displaying of large PDF files.
Sometimes requests will consist of a URL that only contains a directory name. If enabled, directory browsing will create a web page that lists the contents of the directory. This page will only be sent if a default page does not exist in the requested directory.
