TIdEntityHeaderInfo.ContentRangeStart Property

Identifies the beginning byte range in a partial request.

property ContentRangeStart: Int64;

ContentRangeStart is an Int64 property that identifies the beginning byte range requested for a partial entity resource. ContentRangeStart is used with ContentRangeEnd to form the "Content-Range" message header value. 

All ContentRangeStart values are expressed in bytes. 

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.
