2.1. A Simple PATCH Example

2.1. A Simple PATCH Example​

PATCH /file.txt HTTP/1.1
Host: www.example.com
Content-Type: application/example
If-Match: "e0023aa4e"
Content-Length: 100

[description of changes]

This example illustrates use of a hypothetical patch document on an existing resource.

Response:

HTTP/1.1 204 No Content
Content-Location: /file.txt
ETag: "e0023aa4f"

The 204 response code is used because the response does not carry a message body (which a response with the 200 code would have). Note that other success codes could be used as well.

Furthermore, the ETag response header field contains the ETag for the entity created by applying the PATCH, available at http://www.example.com/file.txt, as indicated by the Content-Location response header field.
