I *am* using the document (HTAnchor_setDocument) for this purpose.

Maybe I am just lucky and my application works with current library
(5.0a) and breaks with the next version, or perhaps the following
piece of code (copied from some examples) helps me?

	HTRequest_setReloadMode(obj->request, HT_CACHE_FLUSH);
	if (!HTLoadAnchor((HTAnchor *)obj->anchor, obj->request))

Hopefully, that CACHE_FLUSH disables the check for anchor document in
memory cache filter when I really want to start a new load operation.
