    </code></p></div>

    <p>or</p>

    <div class="example"><p><code>
      apache2 shutdown
    </code></p></div>

    <p>If apache is running in a protected address space specify the
    address space in the unload statement:</p>

    <div class="example"><p><code>
      unload address space = apache2 apache2
    </code></p></div>

    <p>When working with Apache it is important to know how it will
    find the configuration files. You can specify a configuration
    file on the command line in two ways:</p>

    <ul>
      <li><code>-f</code> specifies a path to a particular
      configuration file</li>
    </ul>

    <div class="example"><p><code>
      apache2 -f "vol:/my server/conf/my.conf"
    </code></p></div>

    <div class="example"><p><code>
      apache -f test/test.conf
    </code></p></div>

    <p>In these cases, the proper <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>
    should be set in the configuration file.</p>

    <p>If you don't specify a configuration file name with <code>-f</code>,
    Apache will use the file name compiled into the server, usually
    <code>conf/httpd.conf</code>. Invoking Apache with the <code>-V</code>
    switch will display this value labeled as <code>SERVER_CONFIG_FILE</code>.
    Apache will then determine its <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>
    by trying the following, in this order:</p>

    <ul>
      <li>A <code>ServerRoot</code> directive via a
      <code>-C</code> switch.</li>

      <li>The <code>-d</code> switch on the command line.</li>

      <li>Current working directory</li>

      <li>The server root compiled into the server.</li>
    </ul>

    <p>The server root compiled into the server is usually <code>sys:/apache2</code>.
    invoking apache with the <code>-V</code> switch will display this value labeled as
    <code>HTTPD_ROOT</code>.</p>

    <p>Apache 2.0 for NetWare includes a set of command line directives that can
    be used to modify or display information about the running instance of the
    web server. These directives are only available while Apache is running. Each 
    of these directives must be preceded by the keyword <code>APACHE2</code>.</p>

    <dl>
      <dt>RESTART</dt>
      <dd>Instructs Apache to terminate all running worker
      threads as they become idle, reread the configuration file and restart each
      worker thread based on the new configuration.</dd>

      <dt>VERSION</dt>
      <dd>Displays version information about the currently
      running instance of Apache.</dd>

      <dt>MODULES</dt>
      <dd>Displays a list of loaded modules both built-in
      and external.</dd>

      <dt>DIRECTIVES</dt>
      <dd>Displays a list of all available directives.</dd>

      <dt>SETTINGS</dt>
      <dd>Enables or disables the thread status display
      on the console. When enabled, the state of each running threads is displayed 
      on the Apache console screen.</dd>

      <dt>SHUTDOWN</dt>
      <dd>Terminates the running instance of the Apache
      web server.</dd>

      <dt>HELP</dt>
      <dd>Describes each of the runtime directives.</dd>
    </dl>

    <p>By default these directives are issued against the instance of Apache running
    in the OS address space. To issue a directive against a specific instance running
    in a protected address space, include the -p parameter along with the name of the
    address space. For more information type "apache2 Help" on the command line.</p>

<h2><a name="use" id="use">Configuring Apache for NetWare</a></h2>

    

    <p>Apache is configured by reading configuration files usually stored
    in the <code>conf</code> directory. These are the same as files used 
    to configure the Unix version, but there are a few different directives for
    Apache on NetWare. See the <a href="../">Apache
    documentation</a> for all the available directives.</p>

    <p>The main differences in Apache for NetWare are:</p>

    <ul>
      <li>
        <p>Because Apache for NetWare is multithreaded, it does not
        use a separate process for each request, as Apache does on some Unix
        implementations. Instead there are only threads running: a parent
        thread, and multiple child or worker threads which handle the requests.</p>

        <p>Therefore the "process"-management directives are different:</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#maxrequestsperchild">MaxRequestsPerChild</a></code> -
        Like the Unix directive, this controls how many requests
        a worker thread will serve before exiting. The recommended default,
        <code>MaxRequestsPerChild 0</code>, causes the thread to continue servicing
        request indefinitely. It is recommended on NetWare, unless there is some
        specific reason, that this directive always remain set to <code>0</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#startthreads">StartThreads</a></code> -
        This directive tells the server how many threads it should start initially.
        The recommended default is <code>StartThreads 50</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#minsparethreads">MinSpareThreads</a></code> -
        This directive instructs the server to spawn additional worker threads
        if the number of idle threads ever falls below this value. The recommended
        default is <code>MinSpareThreads 10</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#maxsparethreads">MaxSpareThreads</a></code> -
        This directive instructs the server to begin terminating worker threads
        if the number of idle threads ever exceeds this value. The recommended
        default is <code>MaxSpareThreads 100</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_netware.html#maxthreads">MaxThreads</a></code> -
        This directive limits the total number of work threads to a maximum
        value. The recommended default is <code>ThreadsPerChild 250</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#threadstacksize">ThreadStackSize</a></code> -
        This directive tells the server what size of stack to use
        for the individual worker thread. The recommended default
        is <code>ThreadStackSize 65536</code>.</p>
      </li>

      <li>
        <p>The directives that accept filenames as arguments must use 
        NetWare filenames instead of Unix names. However, because Apache 
        uses Unix-style names internally, forward slashes must be used 
        rather than backslashes. It is recommended that all rooted file paths 
        begin with a volume name. If omitted, Apache will assume the 
        <code>SYS:</code> volume which may not be correct.</p>
      </li>

      <li>
        <p>Apache for NetWare has the ability to load modules at
        runtime, without recompiling the server. If Apache is
        compiled normally, it will install a number of optional
        modules in the <code>\Apache2\modules</code> directory.
        To activate these, or other modules, the <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code> directive
        must be used. For example, to active the status module, use
        the following:</p>

        <div class="example"><p><code>
          LoadModule status_module modules/status.nlm
        </code></p></div>

        <p>Information on <a href="../mod/mod_so.html#creating">creating loadable
        modules</a> is also available.</p>
      </li>
    </ul>

    <h3><a name="use-add" id="use-add">Additional NetWare specific directives:</a></h3>

      

      <ul>
        <li><code class="directive"><a href="../mod/core.html#cgimapextension">CGIMapExtension</a></code> -
        This directive maps a CGI file extension to a script interpreter.</li>
      </ul>
      <ul>
        <li><code class="directive"><a href="../mod/mod_nw_ssl.html#securelisten">SecureListen</a></code> -
        Enables SSL encryption for a specified port.</li>
      </ul>
      <ul>
        <li><code class="directive"><a href="../mod/mod_nw_ssl.html#nwssltrustedcerts">NWSSLTrustedCerts</a></code> -
        Adds trusted certificates that are used to create secure connections to proxied servers.</li>
      </ul>
      <ul>
        <li><code class="directive"><a href="../mod/mod_nw_ssl.html#nwsslupgradeable">NWSSLUpgradeable</a></code> -
        Allow a connection created on the specified address/port to be upgraded to an SSL connection.</li>
      </ul>

<h2><a name="comp" id="comp">Compiling Apache for NetWare</a></h2>

    

    <p>Compiling Apache requires MetroWerks CodeWarrior 6.x or higher. Once 
    Apache has been built, it can be installed to the root of any NetWare 
    volume. The default is the <code>sys:/Apache2</code> directory.</p>

    <p>Before running the server you must fill out the <code>conf</code>
    directory. Copy the file <code>HTTPD-STD.CONF</code> from the distribution
    <code>conf</code> directory and rename it to <code>HTTPD.CONF</code>.
    Edit the <code>HTTPD.CONF</code> file searching for all <code>@@Value@@</code>
    markers and replacing them with the appropriate setting. Copy over
    the <code>conf/magic</code> and <code>conf/mime.types</code> files as well.
    Alternatively, a complete distribution can be built by including the keyword
    <code>install</code> when invoking the makefiles.</p>
