A user agent is a computer program representing a person, for example, a browser in a Web context.
Besides a browser, a user agent could be a bot scraping webpages, a download manager, or another app accessing the Web. Along with each request they make to the server, browsers include a self-identifying User-Agent HTTP header called a user agent (UA) string. This string often identifies the browser, its version number, and its host operating system.
Spam bots, download managers, and some browsers often send a fake UA string to announce themselves as a different client. This is known as user agent spoofing.
A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".
MS Edge Mozilla/5.0 (Windows NT 10.0; Win64; x64) Apple WebKit/537.36 (HTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Edge/16.16299 No wonder MS are stuck with both MSI and Edge.

AD FS 2016 now has an improved default setting that enables the Edge browser to do WIA while not also (incorrectly) catching Windows Phone as well: The above means you no longer have to configure individual user agent strings to support common Edge scenarios, even though they are updated quite often.
By default, a new AD FS installation has a set of user agent string matches created. Particularly, Windows devices have similar user agent strings with minor variations in the tokens.
Rv: gecko version indicates the release version of Gecko (such as 17.0 “). The Chrome (or Chromium/Blink-based engines) user agent string is similar to Firefox’s.
For compatibility, it adds strings like HTML, like Gecko and Safari. The Opera browser is also based on the Blink engine, which is why it almost looks the same, but adds “Or/
In this example, the user agent string is mobile Safari’s version. The software used on a client for sending a request can be a browser, a media player, or a similar program.

You’ve probably been annoyed at one time or another when visiting a website that requires a specific browser.
Luckily, you can fool a website into thinking you’re using a different browser and you can do this with most, including Safari. The solution to this was often to send a false user agent string,” which would fool the web server into delivering you the preferred content.
Today, users are less likely to have a problem since websites and browsers are better at adhering to web standards. If you use Apple OS X’s Safari, here’s how you change the user agent, and even create custom ones as well.
Now Safari will have a new menu devoted solely to development tools. The “Other…” option allows you to specify an user agent other than those listed, such as if you’re curious to see how Google Chrome on an iPad running iOS 8.2 renders, you’d use the appropriate string.
If you have anything you’d like to add, such as a question or a comment, please provide feedback in our discussion forum. Summary: The user agent for IE 11 does not contain MSI anymore, which is a tactic deliberately set by Microsoft IE team.
