#  Accept-Ranges

The **` Accept-Ranges ` ** HTTP response header is a marker used by the server
to advertise its support for partial requests from the client for file
downloads. The value of this field indicates the unit that can be used to
define a range.

In the presence of an ` Accept-Ranges ` header, the browser may try to
_resume_ an interrupted download instead of trying to restart the download.
