What is a browser's user agent?
A user agent is a string sent to the webserver when a page is requested by a browser. User Agent is a request header that is included with other HTTP headers and sent by the browser to identify itself which operating system and type of browser it is. The user agent is sent with every HTTP request it makes to a web server. Each browser provides a built-in user agent string when making a request, but this string can be changed by a user.
