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