Introduction:
 

When you visit a webpage, your browser sends the user-agent string to the server hosting the site that you are visiting. This string indicates which browser you're using, its version number, and details about your system, such as operating system and version. The web server can use this information to provide content that is tailored for your specific browser.

 

Understanding the user-agent string

When you request a webpage, your browser sends a number of headers to the server hosting the site that you're visiting, as shown here.

 
 
GET / HTTP/1.1
Accept: text/html, application/xhtml+xml, */*
Accept-Language: en-US
User-Agent: Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko
Accept-Encoding: gzip, deflate
Proxy-Connection: Keep-Alive


Aruba controller see the string returned by the client and classifies the device type based on the UA string "User-Agent: Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0)"
