Description:

Content negotiation, or more accurately content selection, is the
selection of the document that best matches the clients capabilities,
from one of several available documents. There are two implementations
of this.
- A type map (a file with the handler type-map) which explicitly lists
the files containing the variants.
- A MultiViews search (enabled by the MultiViews Option, where the
server does an implicit filename pattern match, and choose from
amongst the results.
