  <title>Upgrading to 2.0 from 1.3</title>
  
  <summary>
    <p>In order to assist folks upgrading, we maintain a document
    describing information critical to existing Apache users. These
    are intended to be brief notes, and you should be able to find
    more information in either the <a
    href="new_features_2_0.html">New Features</a> document, or in
    the <code>src/CHANGES</code> file.</p>
  </summary>
  
    <section id="compile-time">
      <title>Compile-Time Configuration Changes</title>
  
      <ul>
        <li>Apache now uses an <code>autoconf</code> and
        <code>libtool</code> system for <a
        href="install.html">configuring the build processes</a>.
        Using this system is similar to, but not the same as, using
        the APACI system in Apache 1.3.</li>
  
        <li>In addition to the usual selection of modules which you
        can choose to compile, Apache 2.0 has moved the main part of
        request processing into <a href="mpm.html">Multi-Processing
        Modules</a> (MPMs).</li>
      </ul>
    </section>
  
    <section id="run-time">
      <title>Run-Time Configuration Changes</title>
  
      <ul>
        <li>Many directives that were in the core server in Apache
        1.3 are now in the MPMs. If you wish the behavior of the
        server to be as similar as possible to the behavior of Apache
        1.3, you should select the <a
        href="mod/prefork.html">prefork</a> MPM. Other MPMs will have
        different directives to control process creation and request
        processing.</li>
  
        <li>The <a href="mod/mod_proxy.html">proxy module</a> has been
        revamped to bring it up to HTTP/1.1.  Among the important changes,
        proxy access control is now placed inside a &lt;Proxy&gt; block
        rather than a &lt;Directory proxy:&gt; block.</li>
  
        <li>The handling of PATH_INFO (trailing path information after
        the true filename) has changed for some modules.  Modules
        that were previously implemented as a handler but are now
        implemented as a filter may no longer accept requests with
        PATH_INFO.  Filters such as <a
        href="mod/mod_include.html">INCLUDES</a> are implemented on top
        of the core handler, and therefore reject requests with
        PATH_INFO.  You can use the <directive
        module="core">AcceptPathInfo</directive> directive to
        force the core handler to accept requests with PATH_INFO and
        thereby restore the ability to use PATH_INFO in server-side
        includes.</li>
  
        <li>The <directive
        module="mod_negotiation">CacheNegotiatedDocs</directive>
        directive now takes the argument <code>on</code> or
        <code>off</code>. Existing instances of
        <code>CacheNegotiatedDocs</code> should be replaced with
        <code>CacheNegotiatedDocs on</code>.</li>
  
        <li>
          The <directive module="core">ErrorDocument</directive>
          directive no longer uses a quote at the beginning of the
          argument to indicate a text message. Instead, you should
          enclose the message in double quotes. For example, existing
          instances of
  
          <blockquote>
            <code>ErrorDocument 403 "Some Message</code>
          </blockquote>
          should be replaced with
  
          <blockquote>
            <code>ErrorDocument 403 "Some Message"</code>
          </blockquote>
          As long as the second argument is not a valid URL or
          pathname, it will be treated as a text message.
        </li>
  
        <li>The <code>AccessConfig</code> and
        <code>ResourceConfig</code> directives no longer exist.
        Existing instances of these directives can be replaced with
        the <directive module="core">Include</directive>
        directive which has equivalent functionality. If you were
        making use of the default values of these directives without
        including them in the configuration files, you may need to
        add <code>Include conf/access.conf</code> and <code>Include
        conf/srm.conf</code> to your httpd.conf. In order to assure
        that Apache reads the configuration files in the same order
        as was implied by the older directives, the
        <code>Include</code> directives should be placed at the end
        of httpd.conf, with the one for <code>srm.conf</code>
        preceding the one for <code>access.conf</code>.</li>
  
        <li>The <code>BindAddress</code> and <code>Port</code>
        directives no longer exist.  Equivalent functionality is
        provided with the more flexible
        <directive module="mpm_common">Listen</directive>
        directive.</li>
  
        <li>Another use of the <code>Port</code>
        directive in Apache-1.3 was setting the port number to be used
        in self-referential URL's. The Apache-2.0 equivalent is
        the new <directive module="core">ServerName</directive>
        syntax: it has been changed to allow specifying both the
        hostname <em>and</em> the port number for self-referential URL's
        in one directive.</li>
  
        <li>The <code>ServerType</code> directive no longer exists.
        The method used to serve requests is now determined by the
        selection of MPM. There is currently no MPM designed to be
        launched by inetd.</li>
  
        <li>The mod_log_agent and mod_log_referer modules which
        provided the <code>AgentLog</code>, <code>RefererLog</code>
        and <code>RefererIgnore</code> directives have been removed.
        Agent and referer logs are still available using the
        <directive module="mod_log_config">CustomLog</directive>
        directive of mod_log_config.</li>
  
        <li>The <code>AddModule</code> and
        <code>ClearModuleList</code> directives no longer exist.
        These directives where used to ensure that modules could be
        enabled in the correct order. The new Apache 2.0 API allows
        modules to explicitly specify their ordering, eliminating the
        need for these directives.</li>
  
        <li>The <code>FancyIndexing</code> directive has been removed.
        The same functionality is available through the
        <code>FancyIndexing</code> option to the <directive
        module="mod_autoindex">IndexOptions</directive>
        directive.</li>
      </ul>
    </section>
  
    <section id="misc">
      <title>Misc Changes</title>
  
      <ul>
        <li>The <code>httpd</code> command line option
        <code>-S</code> which was used for printing the virtual host
        configuration has been replaced by <code>-t -D
        DUMP_VHOSTS</code>.</li>
  
        <li>The module mod_auth_digest, which was experimental in
        Apache 1.3, is now a standard module.</li>
  
        <li>The mod_mmap_static module, which was experimental in
        Apache 1.3, has been replaced with mod_file_cache.</li>
  
        <li>The distribution has been completely reorganized so that
        it no longer contains an independent <code>src</code>
        directory. Instead, the sources are logically organized under
        the main distribution directory, and installations of the
        compiled server should be directed to a separate
        directory.</li>
      </ul>

      <title>Third Party Modules</title>
  
      <p>Extensive changes were made to the server API in Apache 2.0.
      Existing modules designed for the Apache 1.3 API will
      <strong>not</strong> work in Apache 2.0 without modification.
      Details are provided in the <a href="developer/">developer
      documentation</a>.</p>
