HTTP | PUT

The HTTP PUT request method is used to create a new resource or overwrite a representation of the target resource that is known by the client. Calling this method once is similar to calling it multiple times successively as it has the same effect. Though it is idempotent, we cannot cache its response. Syntax:

PUT /html file HTTP/1.1

Example: REQUEST:

PUT /example.html HTTP/1.1
Host: sample.com
Content-type: text/html
Content-length: 20

<p>New File</p>

RESPONSE: If the PUT request successfully creates a new resource, then the server informs the user by sending 201(Created) response. Output:

HTTP/1.1 201 Created
Content-Location: /example.html

If the target resource already has a representation and it is successfully modified by the request then the server must send either a 200(OK) or 204(No Content) response indicating that the response is successful. Output:

HTTP/1.1 204 No Content
Content-Location: /newexample.html
