In extreme cases, the viewer would be directed to a different site. This can be examined on the client or server-side and, during the dark days of web development, would be used to modify or provide a different user experience. and pixel ratio (such as 2 for iPhone Retina screens where the pixel density is twice as high as the reported viewport resolution)Īll browsers identify themselves with a user agent string sent on every HTTP header. ![]()
