How the Web site knows what language the browser user is using

We will see a lot of support for multi-language sites, some early sites in the home page will have a link to let users choose to see their own Chinese, or English, now the site is not needed, these sites can be based on the user's language to display a different version of the language. For example, you are using Simplified Chinese, open a Web page, you will see a Simplified Chinese web page, you use English, enter the same address, you will see an English page.

How does the server know which language version of the page the user wants to see?

Browser end

For the site, a site to serve a large amount of users, using the server to remember the user's language is very troublesome, this work or from the browser, if the browser itself told the server want to use the language, the server is not simple?

A variety of browsers can set the language you want to use, in IE, select Settings, pop-up dialog box, you can set language preferences.

Click the language, Pop-up Language Preferences dialog box.
