tus is a HTTP based protocol for resumable file uploads. Resumable means you can carry on where you left off without re-uploading whole data again in case of any interruptions. An interruption may happen willingly if the user wants to pause, or by accident in case of a network issue or server outage.

The example below shows the continuation of a 100 byte upload that was interrupted after 70 bytes were transferred.

Request HEAD /files/24e533e02ec3bc40c387f1a0e460e216 HTTP/1.1 Host: tus.example.org Tus-Resumable: 1.0.0

Response HTTP/1.1 200 OK Upload-Offset: 70 Tus-Resumable: 1.0.0

Given the offset, the Client uses the PATCH method to resume the upload:

PATCH /files/24e533e02ec3bc40c387f1a0e460e216 HTTP/1.1 Host: tus.example.org Content-Type: application/offset+octet-stream Content-Length: 30 Upload-Offset: 70 Tus-Resumable: 1.0.0

[remaining 30 bytes]

HTTP/1.1 204 No Content Tus-Resumable: 1.0.0 Upload-Offset: 100
