most recently, I learned that the browser sends the screen resolution to the sites that the user visits. Right now I am writing a small tool that will help you learn as much information as possible about who visits the test site from which device. And I had a question, how can I find out the screen resolution of the device that visited my site? What does the browser need to request? I am writing on python.

  • разрешение экрана устройства can be sent via js (for example, through the ajax + properties of window.innerWidth and window.innerHeight), but it seems to me that this is not transmitted in the HTTP protocol. - gil9red
