# NegotiatedFrame

A frame that implements HTTP negotiation among a set of variant resources. This frame implements the HTTP/1.0 negotiation algorithm, which is known to be subject to some bugs.

It maintains the list of resources (by their names, see the variants attribute) among which to negotiate. It uses only the standard HTTPFrame attributes to perform the actual negotiation, which can be done based on the variants types, their natural languages, their encodings, or their character sets.
