Answer from AI
The User-Agent header in HTTP requests contains information about the client application sending the request. It is usually a string describing the browser, its version, the operating system, and sometimes the device.
Example of User-Agent:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.93 Safari/537.36
This header helps the server determine which device and browser the request came from, in order to, for example, adapt the page content or track usage statistics.
