A client (e.g. your Web browser or our CheckUpDown robot) can indicate to the Web server characteristics of the data it will accept back from the Web server. This is done using 'accept headers' of the following types:

Accept: The MIME types accepted by the client. For example, a browser may only accept back types of data (HTML files, GIF files etc.) it knows how to process.
Accept-Charset: The character sets accepted by the client.
Accept-Encoding: The data encoding accepted by the client e.g. the file formats it understands.
Accept-Language: The natural languages (English, German etc.) accepted by the client.
Accept-Ranges: Whether the client accepts ranges of bytes from the resource i.e. a portion of the resource. If the Web server detects that the data it wants to return is not acceptable to the client, it returns a header containing the 406 error code.

Apres qu'envoie IE qui plais pas au serveur j'en ai aucune idée...
