Subject cvs commit: apachen/htdocs/manual/mod directive-dict.html directives.html mod_example.html mod_proxy.html
Date Wed, 15 Oct 1997 14:45:27 GMT
coar        97/10/15 07:45:27

  Modified:    htdocs/manual/mod directives.html mod_example.html
                        mod_proxy.html
  Added:       htdocs/manual/mod directive-dict.html
  Log:
  	Clean up some typos in the proxy documentation, and add a
  	dictionary for the directive attributes (status, override,
  	et cetera) - part of the directive-documentation-normalisation
  	effort, and something I've wanted for a long time.  Updated the
  	mod_example page to use the links to the dictionary (as an example ;-).

    <P>
    Each Apache configuration directive is described using a common format
    that looks like this:
    </P>
    <DL>
     <DD><A
          HREF="#Syntax"

    <P>
    Each of the directive's attributes, complete with possible values
    where possible, are described in this document.

    <P>
    This indicates the format of the directive as it would appear in a
    configuration file.  This syntax is extremely directive-specific, so
    refer to the text of the directive's description for details.
    </P>
  
    <HR>
    <H2><A NAME="Default">Default</A></H2>
    <P>
    If the directive has a default value (<EM>i.e.</EM>, if you omit it
    from your configuration entirely, the Apache Web server will behave as
    though you set it to a particular value), it is described here.  If
    there is no default value, this section should say
    &quot;<EM>None</EM>&quot;.
    </P>
  
    <HR>
    <H2><A NAME="Context">Context</A></H2>
    <P>
    This indicates where in the server's configuration files the directive
    is legal.  It's a comma-separated list of one or more of the following
    values:
    </P>
    <DL>
     <DT><STRONG>server config</STRONG>
     </DT>
     <DD>This means that the directive may be used in the server
      configuration files (<EM>e.g.</EM>, <SAMP>httpd.conf</SAMP>,
      <SAMP>srm.conf</SAMP>, and <SAMP>access.conf</SAMP>), but
      <STRONG>not</STRONG> within any <SAMP>&lt;VirtualHost&gt;</SAMP>
or
      &lt;Directory&gt; containers.  It is not allowed in
      <SAMP>.htaccess</SAMP> files at all.
      <P>
      </P>
     </DD>
     <DT><STRONG>virtual host</STRONG>
     </DT>
     <DD>This context means that the directive may appear inside
      <SAMP>&lt;VirtualHost&gt;</SAMP> containers in the server
      configuration files.
      <P>
      </P>
     </DD>
     <DT><STRONG>directory</STRONG>
     </DT>
     <DD>A directive marked as being valid in this context may be used
      inside <SAMP>&lt;Directory&gt;</SAMP> containers in the server
      configuration files.
      <P>
      </P>
     </DD>
     <DT><STRONG>.htaccess</STRONG>
     </DT>
     <DD>If a directive is valid in this context, it means that it can
      appear inside <EM>per</EM>-directory <SAMP>.htaccess</SAMP>
files.
      It may not be processed, though depending upon the
      <A
       HREF="#Override"
       REL="Help"
      >overrides</A>
      currently active.
      <P>
      </P>
     </DD>
    </DL>
    <P>
    The directive is <EM>only</EM> allowed within the designated context;
    if you try to use it elsewhere, you'll get a configuration error that
    will either prevent the server from handling requests in that context
    correctly, or will keep the server from operating at all --
    <EM>i.e.</EM>, the server won't even start.
    </P>
    <P>
    The valid locations for the directive are actually the result of a
    Boolean OR of all of the listed contexts.  In other words, a directive
    that is marked as being valid in &quot;<SAMP>server config,
    .htaccess</SAMP>&quot; can be used in the <SAMP>httpd.conf</SAMP>
file
    and in <SAMP>.htaccess</SAMP> files, but not within any
    &lt;Directory&gt; or &lt;VirtualHost&gt; containers.
    </P>
  
    <HR>
    <H2><A NAME="Override">Override</A></H2>
    <P>
    This directive attribute indicates which configuration override must
    be active in order for the directive to be processed when it appears
    in a <SAMP>.htaccess</SAMP> file.  If the directive's
    <A
     HREF="#Context"
     REL="Help"
    >context</A>
    doesn't permit it to appear in <SAMP>.htaccess</SAMP> files, this
    attribute should say &quot;<EM>Not applicable</EM>&quot;.
    </P>
    <P>
    Overrides are activated by the
    <A
     HREF="core.html#allowoverrides"
     REL="Help"
    ><SAMP>AllowOverrides</SAMP></A>
    directive, and apply to a particular scope (such as a directory) and
    all descendants, unless further modified by other
    <SAMP>AllowOverrides</SAMP> directives at lower levels.  The
    documentation for that directive also lists the possible override
    names available.
    </P>
  
    <HR>
    <H2><A NAME="Status">Status</A></H2>
    <P>
    This indicates how tightly bound into the Apache Web server the
    directive is; in other words, you may need to recompile the server
    with an enhanced set of modules in order to gain access to the
    directive and its functionality.  Possible values for this attribute
    are:
    </P>
    <DL>
     <DT><STRONG>Core</STRONG>
     </DT>
     <DD>If a directive is listed as having &quot;Core&quot; status, that
      means it is part of the innermost portions of the Apache Web server,
      and is always available.
      <P>
      </P>
     </DD>
     <DT><STRONG>Base</STRONG>
     </DT>
     <DD>A directive labeled as having &quot;Base&quot; status is
      supported by one of the standard Apache modules which is compiled
      into the server by default, and is therefore normally available
      unless you've taken steps to remove the module from your configuration.
      <P>
      </P>
     </DD>
     <DT><STRONG>Extension</STRONG>
     </DT>
     <DD>A directive with &quot;Extension&quot; status is provided by one
      of the modules included with the Apache server kit, but the module
      isn't normally compiled into the server.  To enable the directive
      and its functionality, you will need to change the server build
      configuration files and re-compile Apache.
      <P>
      </P>
     </DD>
     <DT><STRONG>Experimental</STRONG>
     </DT>
     <DD>&quot;Experimental&quot; status indicates that the directive is
      available as part of the Apache kit, but you're on your own if you
      try to use it.  The directive is being documented for completeness,
      and is not necessarily supported.  The module which provides the
      directive may or may not be compiled in by default; check the top of
      the page which describes the directive and its module to see if it
      remarks on the availability.
      <P>
      </P>
     </DD>
    </DL>
  
    <HR>
    <H2><A NAME="Module">Module</A></H2>
    <P>
    This quite simply lists the name of the source module which defines
    the directive.
    </P>
  
    <HR>
    <H2><A NAME="Compatibility">Compatibility</A></H2>
    <P>
    If the directive wasn't part of the original Apache version 1
    distribution, the version in which it was introduced should be listed
    here.  If the directive has the same name as one from the NCSA HTTPd
    server, any inconsistencies in behaviour between the two should also
    be mentioned.  Otherwise, this attribute should say &quot;<EM>No
    compatibility issues.</EM>&quot;
