ParseRanges()

MythHTTPStatus MythHTTPRanges::ParseRanges ( const QString &  Request, int64_t  TotalSize, HTTPRanges &  Ranges, int64_t &  PartialSize  )

staticprotected

Parse a range request header.

Note

If we fail to parse the header, we return HTTP 200 and the range request is effectively ignored. We return HTTP 416 Requested Range Not Satisfiable where it is parsed but is invalid. If parsed and valid, we return HTTP 206 (Partial Content).

Todo:

Per the specs, sending complicated range requests could potentially be used as part of a (D)DOS attack and it is suggested that various complicated requests are rejected. Probably unnecessary here.
