Yes, the points of the memory cache handler is that the document is in
memory in a form that is already passed - for example as an HTML tree or
as an image map. The application defines what a document looks like as
libwww doesn't know about documents as such.

This method can be used by the application to indicate to the anchor
object that it has the "document" (the parsed representation). The memory
cache will look for this pointer but will of course not understand the
specific document structure. Therefore, all it does it to look at the
anchor, if there is a document associated with the anchor then it says
that the document is already in memory, otherwise it continues to try and
go get it (which could then be from the local file cache etc.)
