	Reading section 5.2 and 5.3, I had a similar question about
the interaction of the receipt of an absoluteURI and the lack of a
HOST header.  The first bullet in 5.2 can be read to imply that an
origin server which receives a Request-URI which is an absoluteURI and
no HOST header should return the resource named in the
Request-URI. This reading is possible because the first bullet states
that any HOST header MUST be ignored when the Request-URI is an
absoluteURI.  Section 14.23 states, however, that any HTTP/1.1 request
without a HOST header must get a 400 status code in the response.
Either we need to put an "unless the Request-URI is an absoluteUri"
into 14.23, or we need to add something to section 5.2 which makes it
clear that there must be a host header for the origin server to
ignore, even if the Request-URI is an absoluteURI.

! The original consensus seemed to be to require the host header all
! the time (per Klensin's original recommendations), but Roy successfully 
! argued us (in the Palo Alto meeting) around to a more slightly more
! loose definition, by promising he'd personally make sure that Apache correctly
! implemented the host requirements and report errors properly
! (that host information always be present), to address
! John Klensin and my strongly held opinion that it is vital that
! any errors in the host requirements get detected and reported quickly
! to the developer community so that no buggy clients become widespread
! that do not provide host informationconform.  With Apache's large server market
! share (and prompt implementation history), I became comfortable with the 
! less restrictive requirement on host.  So given that, I'm adding the 
! "unless the Request-URI is an absoluteURI" to 14.23 rather than the 
! latter solution.
! If Roy doesn't do it right (or do it at all...) I'll borrow John's
! infamous ax (and then hand it back to John to use on me).
