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".

Unfortunately, the Opera developers started to experience strange problems with a selection of sites that use browser sniffing to serve version-specific content and/or scripts. Worse still, many of these sites decided that the browser was unsupported and refused to provide any content.

The Opera team deliberated the site compatibility problem and came up with the best compromise: freeze the first part of the string at 9.80 but append the real version number to the end. V9.80 was chosen rather than v.9.99 just in case there is a need to update the initial version number at a future date.
