206 Partial Content

The server is delivering only part of the resource due to a Range header from the client.

What it means

HTTP 206 is returned when the client uses a Range header to request a specific byte range of a resource. Essential for video streaming, resumable downloads, and large-file delivery.

When it's used

Video/audio streaming, resumable file downloads, parallel chunked downloads.

Common causes
  • HTML5 video player requested a byte range for seeking
  • Download manager resuming an interrupted transfer
  • BitTorrent-style chunked download client
How to fix it
  • Not an error — confirms range serving
  • Ensure your server supports Accept-Ranges: bytes for media files
  • Verify Content-Range header is correctly formatted (e.g., bytes 0-1023/146515)
Example response
HTTP/1.1 206 Partial Content
Content-Range: bytes 0-1023/146515
Content-Length: 1024
