However, for browsers on mobile devices (and at least one on the desktop), the language preferences are likely to be determined by the operating system settings, or in some cases by the language of the system when you installed the browser.īrowsers that allow you to change your language preferences will generally allow you to specify a list of languages, so that if your first choice is not available you can say what alternative languages to try, and in what order. See the next section for examples of how to change these settings. These tell the server what language you prefer for pages and resources that it sends you (separately from the language of the browser user interface). Most desktop browsers have settings that allow you to check or change the language preference settings.

The browser settings discussed here do not affect content negotiation based on this kind of mechanism. For example, Google tends to use IP information to determine the language you will receive. Sometimes a server may determine which language to send to you in a way that doesn't rely on the Accept-Language information.
