The User-Agent string is very useful because it gives you information about the software and hardware running on the device making the request. You can make important decisions on how to handle web traffic based on the User-Agent string, ranging from simple segmentation and redirection, to more complex content adaptation and device targeting decisions.

Even more information, such as carrier ID, screen resolution, CPU and storage capacity can be returned when the User-Agent string is mapped to an additional set of data, returned in real-time.
