Update file for MUSIC/SP 6.2 Demo system:  upd2.mfarc


Prerequisites:  UPD1

This update contains:

- Improvements to HTTPD (web server): When an abbreviated URL
  is automatically extended by the server, the server now gives
  response code 303 (redirection), along with a "Location:" header
  record which tells the browser the full URL. This allows the
  browser to redo the request with the full URL, and allows the
  browser to correctly resolve relative URI's in the HTML file.
  This is similar to what most other modern web servers do.
  This change makes it possible to write MUSIC/SP HTML pages that
  can be more easily moved to another server without file changes.
  For example, an abbreviated URL like http://www.site.com/user1
  is usually expanded by MUSIC/SP's HTTPD to something like
  http://www.site.com/user1/http/home.htm, and HTTPD now gives
  a 303 response. Previously, the page was served without a 303,
  and the HTML file had to contain a <base> tag. Also, a new
  option -BASE is supported in the $tcp:http.aliases file, and
  some minor problems have been fixed in HTTPD.

- Improvements to MUSIC/SP's text-mode web browser (WEB program):
  It now resolves the special directory names ".." and "." in the
  file path part of the URL. A "Host:" header record (which is
  required by some web sites) is now included in the HTTPD request.
  Some minor bugs have been fixed.

- FTP server (FTPD): A new namelist parameter, FILTER='filename',
  is now supported. The specified filter file allows FTP clients
  to be filtered (allowed or denied connection) by IP address.
  See $tcp:ftpd.filter.samp .  Also, a new IF command is supported
  by the server. See the description in $tcp:ftpd_info.txt and
  $tcp:ftphelp.txt . The IF command allows the client to test
  whether a specified file on the server exists and is GET'able.
  The IF command is useful in automated scripts on the client side,
  for example for automatic backup of MUSIC/SP files to a storage
  device.

- MFCHEK utility: New namelist parameter DATES=T/F has been added.
  If DATES=T is specified, the date-updated and updater userid are
  displayed for each file in the archive.

- Some new or updated documentation files are included.
