What is a User Agent identifier

Every computer or mobile device should set an data field called User-Agent when getting a page, or making a request, to a website. This is a header field that contains a free-form ASCII string designed to uniquely identify the user agent making the request. In general the string provides information about the user computer or mobile device's software & hardware, a particular information about the browser being used.

The can serve as a fingerprint of the user agent making the request. Consequently, it is not possible to consistently extract detailed information about the device from the User-Agent header value alone. For instance, there is no indication in this string whether the requesting device supports certain features. This information is determined with other methods. However, knowing something about the device and browser can provide insight into the device's capabilities. This is particularly useful for handling requests from mobile devices, where limitations such as screen size can be important to consider.

Currently, storing or tracking the User Agent string without consent is not specifically forbidden by the major data-protection laws. Though as we mentioned above, the User Agent string can server as a fingerprint and tracking it in certain circumstances may contravene the spirit of data protection laws.
