Update of /cvsroot/othersrc/external/bsd/httpdev
In directory ivanova.netbsd.org:/tmp/cvs-serv2020

Log Message:
httpdev is a (very) small utility which allows a remote file to appear
as a local one, just like iscsi-initiator(8).  However, unlike iSCSI,
httpdev uses HTTP as a transport, so the remote end only requires a
web server.  The local end just requires the ability to issue
partial-range HTTP commands and read responses.  To do that, I wrote a
minimalist HTTP client library, although any such library could be
used.  Again, in contrast to iSCSI, no special protocol is used, there
is no encapsulation of SCSI commands, and no framing of blocks, and no
needless synthesis of SCSI commands in the initiator, or
interpretation of SCSI commands in the target.  Discovery requires no
login - either one can access a file on a webserver, or one can't.

To illustrate its use, the following commands should show how to use
the daily ISO images on nyftp to be read as an ISO image on the local
machine.

httpdev uses refuse(3) and the virtdir(3) routines, and a small http
client library I wrote.  If that was replaced with libcurl, then
httpdev could also take advantage of https (assuming we trust the
CAs...)

As for size:

% size ./httpdev
   text   data    bss     dec      hex   filename
  15065   1328   1128   17521   0x4471   ./httpdev
%

If someone were wanting to distribute a new release of an operating
system, httpdev could be very useful for accessing ISO images on a
central webserver, for example. Just saying...
