What is an user agent?

A user agent (or useragent/user-agent) is the browser that you use to view this site. When a software agent operates in a network protocol, it often identifies itself, its application type, operating system, software vendor, or software revision, by submitting a characteristic identification string to its operating peer. A website needs to know who you are, looking for a browser user agent. This information is sent with each and every request from your browser.
