This 54 improves scalability for many, but not all configurations.</dd> 55 56 <dt>New Build System</dt> 57 58 <dd>The build system has been rewritten from scratch to be 59 based on <code>autoconf</code> and <code>libtool</code>. 60 This makes Apache's configuration system more similar to 61 that of other packages.</dd> 62 63 <dt>Multiprotocol Support</dt> 64 65 <dd>Apache now has some of the infrastructure in place to 66 support serving multiple protocols. <code class="module"><a href="./mod/mod_echo.html">mod_echo</a></code> has 67 been written as an example.</dd> 68 69 <dt>Better support for non-Unix 70 platforms</dt> 71 72 <dd>Apache 2.0 is faster and more stable on non-Unix 73 platforms such as BeOS, OS/2, and Windows. With the 74 introduction of platform-specific <a href="mpm.html">multi-processing modules</a> (MPMs) and the 75 Apache Portable Runtime (APR), these platforms are now 76 implemented in their native API, avoiding the often buggy and 77 poorly performing POSIX-emulation layers.</dd> 78 79 <dt>New Apache API</dt> 80 81 <dd>The API for modules has changed significantly for 2.0. 82 Many of the module-ordering/-priority problems from 1.3 should 83 be gone. 2.0 does much of this automatically, and module ordering 84 is now done per-hook to allow more flexibility. Also, new calls 85 have been added that provide additional module capabilities 86 without patching the core Apache server.</dd> 87 88 <dt>IPv6 Support</dt> 89 90 <dd>On systems where IPv6 is supported by the underlying 91 Apache Portable Runtime library, Apache gets IPv6 listening 92 sockets by default. Additionally, the <code class="directive"><a href="./mod/mpm_common.html#listen">Listen</a></code>, <code class="directive"><a href="./mod/core.html#namevirtualhost">NameVirtualHost</a></code>, and <code class="directive"><a href="./mod/core.html#virtualhost">VirtualHost</a></code> directives support 93 IPv6 numeric address strings (e.g., "<code>Listen 94 [2001:db8::1]:8080</code>").</dd> 95 96 <dt>Filtering</dt> 97 98 <dd>Apache modules may now be written as filters which act on 99 the stream of content as it is delivered to or from the 100 server. This allows, for example, the output of CGI scripts to 101 be parsed for Server Side Include directives using the 102 <code>INCLUDES</code> filter in <code class="module"><a href="./mod/mod_include.html">mod_include</a></code>. The 103 module <code class="module"><a href="./mod/mod_ext_filter.html">mod_ext_filter</a></code> allows external programs to 104 act as filters in much the same way that CGI programs can act as 105 handlers.</dd> 106 107 <dt>Multilanguage Error Responses</dt> 108 109 <dd>Error response messages to the browser are now provided in 110 several languages, using SSI documents. They may be customized 111 by the administrator to achieve a consistent look and feel.</dd> 112 113 <dt>Simplified configuration</dt> 114 115 <dd>Many confusing directives have been simplified. The often 116 confusing <code>Port</code> and <code>BindAddress</code> directives 117 are gone; only the <code class="directive"><a href="./mod/mpm_common.html#listen">Listen</a></code> 118 directive is used for IP address binding; the <code class="directive"><a href="./mod/core.html#servername">ServerName</a></code> directive specifies the 119 server name and port number only for redirection and vhost 120 recognition.</dd> 121 122 <dt>Native Windows NT Unicode Support</dt> 123 124 <dd>Apache 2.0 on Windows NT now uses utf-8 for all filename 125 encodings. These directly translate to the underlying Unicode 126 file system, providing multilanguage support for all Windows 127 NT-based installations, including Windows 2000 and Windows XP. 128 <em>This support does not extend to Windows 95, 98 or ME, which 129 continue to use the machine's local codepage for filesystem 130 access.</em></dd> 131 132 <dt>Regular Expression Library Updated</dt> 133 134 <dd>Apache 2.0 includes the <a href="http://www.pcre.org/">Perl 135 Compatible Regular Expression Library</a> (PCRE). All regular 136 expression evaluation now uses the more powerful Perl 5 137 syntax.</dd> 138 139 </dl> 140 </div><div class="top"><a href="#page-header"><img alt="top" src="./images/up.gif" /></a></div> 141 <div class="section"> 142 <h2><a name="module" id="module">Module Enhancements</a></h2> 143 144 145 <dl> 146 <dt><code class="module"><a href="./mod/mod_ssl.html">mod_ssl</a></code></dt> 147 148 <dd>New module in Apache 2.0.

In addition, new 198 <code class="directive"><a href="./mod/mod_proxy.html#proxy"><Proxy></a></code> 199 configuration sections provide more readable (and internally 200 faster) control of proxied sites; overloaded <code><Directory 201 "proxy:..."></code> configuration are not supported.

In addition, the 211 negotiation and MultiViews algorithms have been cleaned up to 212 provide more consistent results and a new form of type map that 213 can include document content is provided.</dd> 214 215 <dt><code class="module"><a href="./mod/mod_autoindex.html">mod_autoindex</a></code></dt> 216 217 <dd>Autoindex'ed directory listings can now be configured to 218 use HTML tables for cleaner formatting, and allow finer-grained 219 control of sorting, including version-sorting, and wildcard 220 filtering of the directory listing.</dd> 221 222 <dt><code class="module"><a href="./mod/mod_include.html">mod_include</a></code></dt> 223 224 <dd>New directives allow the default start and end tags for SSI elements 225 to be changed and allow for error and time format configuration 226 to take place in the main configuration file rather than in the 227 SSI document.
