This is an ArsDigita distribution of AOLserver 3.0 (patchlevel 6). It returns

  Server: AOLserver/3.0+ad6

as an HTTP header. It includes the following patches:

- Patches to the ADP parser (karlg@arsdigita.com, jgdavidson@aol.com,
  mcazzell@lovemail.com).
- An extra Ns_CloseOnExec on line 171 of nsd/binder.c to fix a problem where
  child processes of nsd remained bound to a TCP port even after the nsd
  terminated (jsalz@mit.edu).
- A patch to _ns_dirlist in fastpath.tcl to remove a trailing slash in the base
  HREF URL, which was causing ".." in directory listing to be linked
  improperly (jsalz@mit.edu).
- Patches to make Ns_ConnGet work outside of a connection thread
  (markd@arsdigita.com).
- A patch to adp.c to preserve the input to ns_adp_parse -string: ns_adp_parse
  was writing nulls into the input string (rhs@mit.edu).
- Patches for Win32 support (curtisg@arsdigita.com).
- A patch to form.tcl to work around an IE5 bug where:
    1. we deliver a page with a <form method=post enctype=multipart/form-data>
    2. the user submits the form, and IE correctly sends a POST request with
       content-type of multipart/form-data
    3. we issue a 302 redirect
    4. IE sends a GET request with an incorrect content-type of
       multipart/form-data, causing ns_getform to ignore the query portion of
       the URL
  (jbank@arsdigita.com, jsalz@mit.edu)
- A patch to http.tcl correcting the way headers were sent by ns_httpopen
  (jsalz@mit.edu).

New in ad5:

- Patches to support character encodings.  Described in
  encoding-doc.html.  (mayoff@arsdigita.com)
- Patch for a buffer overrun in keepalive.c when keepalive is enabled
  but maxkeep == 0.  (mayoff@arsdigita.com)

New in ad6:

- Patch to nsd/random.c to avoid an occasional deadlock when seeding the
  random number generator.
- Patch tcl/form.tcl prevent multipart/form-data corruption due to EOL
  translation
- Patch nsd/fastpath.c and nsd/return.c to avoid encoding translation
  when sending disk files directly
- Add note in win32/README about need to copy encoding to install directory 
  for Windows source distribution.
