modules and removing the deleted ones; renaming mod_auth_anon->mod_authn_anon, and mod_access->mod_authz_host. All docs to the old modules are now deleted. Translations were kept with their old modules. (Can't read Japanese.) git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@97123 13f79535-47bb-0310-9956-ffa450edef68

<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>

|
|
|
|
|
|
<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>
|
|
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="run-time" id="run-time">Run-Time Configuration Changes</a></h2>
|
|
|
|
|
|
<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 <Proxy> block
|
|
rather than a <Directory proxy:> 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 <code class="directive"><a href="../mod/core.html#acceptpathinfo">AcceptPathInfo</a></code> 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 <code class="directive"><a href="../mod/mod_negotiation.html#cachenegotiateddocs">CacheNegotiatedDocs</a></code>
|
|
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 <code class="directive"><a href="../mod/core.html#errordocument">ErrorDocument</a></code>
|
|
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
|
|
|
|
<div class="example"><p><code>
|
|
ErrorDocument 403 "Some Message
|
|
</code></p></div>
|
|
should be replaced with
|
|
|
|
<div class="example"><p><code>
|
|
ErrorDocument 403 "Some Message"
|
|
</code></p></div>
|
|
|
|
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 <code class="directive"><a href="../mod/core.html#include">Include</a></code>
|
|
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
|
|
<code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code>
|
|
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 <code class="directive"><a href="../mod/core.html#servername">ServerName</a></code>
|
|
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
|
|
<code class="directive"><a href="../mod/mod_log_config.html#customlog">CustomLog</a></code>
|
|
directive of <code class="module"><a href="../mod/mod_log_config.html">mod_log_config</a></code>.</li>
|
|
|
|
<li>The <code>AddModule</code> and
|
|
<code>ClearModuleList</code> directives no longer exist.
|
|
These directives were 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 <code class="directive"><a href="../mod/mod_autoindex.html#indexoptions">IndexOptions</a></code>
|
|
directive.</li>
|
|

|
|
|
|
|
|
<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 <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>, which was
|
|
experimental in Apache 1.3, is now a standard module.</li>
|
|
|
|
<li>The <code>mod_mmap_static</code> module, which was experimental in
|
|
Apache 1.3, has been replaced with <code class="module"><a href="../mod/mod_file_cache.html">mod_file_cache</a></code>.</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>

<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.
