User Agent Strings

User-agent strings act as a method to fingerprint a client. These characteristics range from identifying the browser to the type of OS that it is running on. The user agent string is simply a line of text that is returned whenever your browser connects to a website. The user agent string is based on the specific browser you are using and the OS that is installed on your computer.

For this assignment, you will get hands-on experience with user agent strings and browser fingerprinting.
