Peter,

Your www program is not contacting a www server at all. When the
document address specifies "news:..." the it talks NNTP.
NNTP says nothing about how articles are stored, but allows
one to ask for them by Message-id. Sounds like your newsreader
doesn't have the articles. There should be an error message.
Try
www -v news:a7fd5104@random.se
to see what is going on.

I have found a problem in retrieving news thru both www (linemode)
and
xmosaic. Both correctly pick up my news server name, and if I follow
the
links from `By Type' thru `Network News' to a specific group, both
programs
correctly list the articles, but cannot access the article texts,
giving
me instead the message `Connecting to NewsHost ...' and then coming
back
with `Back, Quit or Help:'

It is clear that both programs are expecting articles to be stored in
files
with names set to the message-id. I have never encountered a system
which
does this, and my own server runs plain vanilla nntp and Cnews, which
puts
articles in files whose names are the article numbers (sequential,
1+).

As the www server is capable of finding the directory (and is
presumably
grepping for 'Subject:' and piping the results back into HTML---or is
it
actually opening each file in turn?) could not a simple addition to
the code
see if the files are named (=message-ID) or numbered
(=message-number) and
act accordingly?

If this is not possible, where do I find a news system which stores
articles
under message-ID filenames instead?
