Server-driven Negotiation : If the selection of the best representation for a response is made by an algorithm located at the server,
|
||||
it is called server-driven negotiation. Selection is based on the available representations of the response (the dimensions over which it can vary; e.g. language, content-coding, etc.)
|
||||
and the contents of particular header fields in the request message or on other information pertaining to the request (such as the network address of the client).
|
||||
Server-driven negotiation is advantageous when the algorithm for selecting from among the available representations is difficult to describe to the user agent,
|
||||
or when the server desires to send its "best guess" to the client along with the first response (hoping to avoid the round-trip delay of a subsequent request if the "best guess" is good enough for the user).
|
||||
In order to improve the server's guess, the user agent MAY include request header fields (Accept, Accept-Language, Accept-Encoding, etc.) which describe its preferences for such a response.
