That is why I checked if it was defined first.  The spec says that not
having a Transfer-Encoding of 'chunked' last is o.k. if there is also a
Connection: close.

'http_connection' should be set by HTTP::Headers, or is there a better
way to get this header in Methods.pm?  (The previous line checked for
'http_te' so i just followed suit...)

Ah...there is a 'transparent' caching proxy server for the campus.  Not
too transparent, eh?

=46rom other hosts not behind the UW proxy I see the same behavior you
see.  LWP 5.65 - 5.69 on debian and redhat.

Nonetheless I think the response I am seeing (after proxy munging) is
valid so shouldn't generate an error.
