The Sec-CH-UA-Platform-Version user agent client hint request header provides the version of the operating system on which the user agent is running.

Syntax

Sec-CH-UA-Platform-Version: <version>

Directives

<version>

The version string typically contains the operating system version in a string, consisting of dot-separated major, minor and patch version numbers. For example, "11.0.0"

The version string on Linux is always empty.

Examples

A server requests the Sec-CH-UA-Platform-Version header by including the Accept-CH in a response to any request from the client, using the name of the desired header as a token:

HTTP/1.1 200 OK
Accept-CH: Sec-CH-UA-Platform-Version

The client may choose to provide the hint, and add the Sec-CH-UA-Platform-Version header to subsequent requests. For example, the following request headers might be sent from a browser running on Windows 10.

GET /GET /my/page HTTP/1.1
Host: example.site

Sec-CH-UA: " Not A;Brand";v="99", "Chromium";v="96", "Google Chrome";v="96"
Sec-CH-UA-Mobile: ?0
Sec-CH-UA-Platform: "Windows"
Sec-CH-UA-Platform-Version: "10.0.0"
