Provide a site-configurable message database.  This is particularly directed
towards non-English language sites.  No attempt has been made to completely
internationalize the server, only messages the average client is likely to be
exposed to are currently provided.

The only way of reloading the database is to restart the server. This is not
of great concern for once customized the messages should remain completely
stable between releases.

When multiple languages are configured the message language processing may be
observed using the WATCH response-header item.


MULTIPLE LANGUAGE SPECIFICATIONS
--------------------------------
Multiple language messages can be specified in two ways:

  1) within the one file
  2) in multiple files specified by a multivalued logical name

Within The One File
~~~~~~~~~~~~~~~~~~~
Language availability is specified through the use of [Language] directives. 
These must be numbered from 1 to the count of those supplied.  The highest
numbered language must have the complete set of messages for this is the
fallback when obtaining any message (this would normally be 'en').  The
[Language] may be specified as a comma-separated list of equivalent or similar
specifications, which during request processing will be matched against a
client specified list of accepted-languages one at a time in specified order. 
A wildcard may be specified which matches all fitting the template.  In this
manner a single language can be used also to match minor variants or language
specification synonyms.

  [Version]  9.0
  [Language]  1  es,es-ES
  [Language]  2  de,de-*
  [Language]  3  en

In the above (rather contrived) example a client request with

  Accept-Language: es-ES,de;q=0.6,en;q=0.3

would have language 1 selected, a client with

  Accept-Language: de-ch,es;q=0.6,en;q=0.3

language 2 selected, with

  Accept-Language: pt-br,de;q=0.6,en;q=0.3

also language 2 selected, with

  Accept-Language: pt

language 3 (the default) selected, etc.

Note that the messages for each language must use the *first* language
specification provided in the [Language] list.  In the example above all
messages for language 1 would be introduced using 'es', for language 2 with
'de' and for language 3 with 'en'.

Multiple Files - Multivalued Logical Name
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
With this approach a logical name containing multiple file names is defined
(more commonly described as a logical search list).  The final file specified
must contain the full message set.  Files specified prior to this, can contain
as many or as few of the full set as is desired.  A [Language] number does not
need to be specified as they are processed in the order the logical name
specifies them in.  Other language file directives are required.

The following is an example of a logical name providing the same three
languages in the examples above.

  $ DEFINE /SYSTEM WASD_CONFIG_MSG WASD_ROOT:[LOCAL]HTTPD$MSG_ES.CONF, -
                                   WASD_ROOT:[LOCAL]HTTPD$MSG_DE.CONF, -
                                   WASD_ROOT:[LOCAL]HTTPD$MSG.CONF

The file contents would be as follows (very contrived examples :-)

  # HTTPD$MSG_ES.CONF
  [Version]  9.0
  [Language]  0  es,es-ES
  [auth]
  es 01  Habla Espanol
  es 02  Habla Inglesi
  [dir]
  es 03  Habla Espanol
  es 04  Habla Inglesi

  # HTTPD$MSG_DE.CONF
  [Version]  9.0
  [Language]  0  de,de-*
  [auth]
  de 01  Sprechen Sie Deutsches
  de 02  Sprechen Sie Englisch
  [dir]
  de 03  Sprechen Sie Deutsches
  de 04  Sprechen Sie Englisch

  # HTTPD$MSG.CONF
  [Version]  9.0
  [Language]  0  en
  [auth]
  .
  .
  .(full set of messages)

The major ADVANTAGE of maintaining multiple files in this way is there is no
need to MERGE files when a new revision is required.  Just update the version
number and add any new required messages to the existing secondary file.
messages to the existing


ADDITIONAL [LANGUAGE] PARAMETERS
--------------------------------
Two optional parameters can follow the language number and language
specification synonym.  The first is a character set to be associated with the
message set.  This is specified using the keyword 'charset=' followed by the
character set specification.  For example

  [Language]  2  charset=ISO-8859-5

The second optional parameter is a comma-separated list of host domain
specifications that the message set can be associated with.  If there is no
"Accept-Language:" list associated with the request then this information will
be used to select the message set.  For example

  [Language]  2  charset=ISO-8859-5  hosts=cz,cz-*


CURRENT MESSAGE GROUPINGS
-------------------------

  [auth]        authentication/authorization
  [dir]         directory listing
  [general]     messages belonging to no particular module or category
  [htadmin]     authentication database administration
  [http]        http status messages
  [mapping]     mapping rules
  [proxy]       proxy module
  [put]         PUT/POST module
  [request]     request acceptance and initial parsing
  [script]      DCL/scripting module
  [ssi]         Server Side Includes
  [status]      error and other status reporting
  [upd]         update module
