What Does Your User Agent Say About You?

Archive

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.

The user agent string can be accessed with JavaScript on the client side using the navigator.userAgent property.

A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".

While all phones come with pre-installed browsers, both Google Play and Apple App Store offer a number of alternative browsers, some focusing on speed and lightness, others on saving bandwidth and blocking ads, and an ever-increasing amount claiming to increase privacy and reduce a users' mobile digital footprint.

Unfortunately, that doesn't sound like official support is high on the company's priority list, but it also doesn't seem like there's any catch or known problem that would hinder you from enjoying your in-browser gaming session via the described method. And since streaming already works so well with the spoofed user agent, I wouldn't be surprised if Nvidia eventually decides to make its service officially available through browsers, just like Stadia.

A UA string is a piece of text that browsers send to websites when they initiate a connection. The UA string contains details about the browser type, rendering engine, and operating system.

For decades, websites have used UA strings to fine-tune features based on a visitor's technical specifications. For starters, UA strings have been used by online advertisers as a way to track and fingerprint website visitors.
