TIdEntityHeaderInfo.ContentRangeStart
Identifies the beginning byte range in a partial request.

property ContentRangeStart: Cardinal;
Description
ContentRangeStart is a Cardinal property that identifies the beginning byte range requested for a partial entity resource. ContentRangeStart is used with ContentRangeEnd to reveal the "Content-Range" message header value.

All ContentRangeStart values are expressed in bytes.

Note: clients cannot depend on servers to send a "416 Requested range not satisfiable" response instead of a "200 (OK)" response for an unsatisfiable request with ContentRangeStart and ContentRangeEnd values, since not all servers implement this request-header.
