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.
|Header type||Response header|
|Forbidden header name||no|
Accept-Ranges: <range-unit> Accept-Ranges: none
Indicates that no range unit is supported. This makes the header equivalent of its own absence and is therefore, rarely used. Although in some browsers, like IE9, this setting is used to disable or remove the pause buttons in the download manager.
