The HTTP User-Agent request header is a characteristic string that lets servers and network peers identify the application, operating system, vendor, and/or version of the requesting user agent. Warning: See Browser detection using the user agent for reasons why serving different content to different browsers is usually a bad idea.
On the Web, a user agent is a software agent responsible for retrieving and facilitating end-user interaction with Web content. [1] This includes all web browsers, such as Google Chrome and Safari, some email clients, standalone download managers like youtube-dl, and other command-line utilities like cURL. [2]The user agent is the client in a client-server system.

The User-Agent (UA) string is contained in the HTTP headers and is intended to identify devices requesting online content. The User-Agent tells the server what the visiting device is (among many other things) and this information can be used to determine what content to return.
All user agent strings that include the substring Chrome indicate a Chrome browser. One of the biggest problems with browser detection based on UA strings is that browsers and user agents routinely pretend to be another browser, or include information based on multiple browsers. The lookbehind feature is always available if the browser is Chrome.
