| <div class="section"> |
| <h2><a name="core" id="core">Core Enhancements</a></h2> |
| |
| |
| <dl> |
| <dt>Unix Threading</dt> |
| |
| <dd>On Unix systems with POSIX threads support, Apache can |
| now run in a hybrid multiprocess, multithreaded mode. This |
| improves scalability for many, but not all configurations.</dd> |
| |
| <dt>New Build System</dt> |
| |
| <dd>The build system has been rewritten from scratch to be |
| based on <code>autoconf</code> and <code>libtool</code>. |
| This makes Apache's configuration system more similar to |
| that of other packages.</dd> |
| |
| <dt>Multiprotocol Support</dt> |
| |
| <dd>Apache now has some of the infrastructure in place to |
| support serving multiple protocols. <code class="module"><a href="./mod/mod_echo.html">mod_echo</a></code> has |
| been written as an example.</dd> |
| |
| <dt>Better support for non-Unix |
| platforms</dt> |
| |
| <dd>Apache 2.0 is faster and more stable on non-Unix |
| platforms such as BeOS, OS/2, and Windows. With the |
| introduction of platform-specific <a href="mpm.html">multi-processing modules</a> (MPMs) and the |
| Apache Portable Runtime (APR), these platforms are now |
| implemented in their native API, avoiding the often buggy and |
| poorly performing POSIX-emulation layers.</dd> |
| |
| <dt>New Apache API</dt> |
| |
| <dd>The API for modules has changed significantly for 2.0. |
| Many of the module-ordering/-priority problems from 1.3 should |
| be gone. 2.0 does much of this automatically, and module ordering |
| is now done per-hook to allow more flexibility. Also, new calls |
| have been added that provide additional module capabilities |
| without patching the core Apache server.</dd> |
| |
| <dt>IPv6 Support</dt> |
| |
| <dd>On systems where IPv6 is supported by the underlying |
| Apache Portable Runtime library, Apache gets IPv6 listening |
| 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 |
| IPv6 numeric address strings (e.g., "<code>Listen |
| [2001:db8::1]:8080</code>").</dd> |
| |
| <dt>Filtering</dt> |
| |
| <dd>Apache modules may now be written as filters which act on |
| the stream of content as it is delivered to or from the |
| server. This allows, for example, the output of CGI scripts to |
| be parsed for Server Side Include directives using the |
| <code>INCLUDES</code> filter in <code class="module"><a href="./mod/mod_include.html">mod_include</a></code>. The |
| module <code class="module"><a href="./mod/mod_ext_filter.html">mod_ext_filter</a></code> allows external programs to |
| act as filters in much the same way that CGI programs can act as |
| handlers.</dd> |
| |
| <dt>Multilanguage Error Responses</dt> |
| |
| <dd>Error response messages to the browser are now provided in |
| several languages, using SSI documents. They may be customized |
| by the administrator to achieve a consistent look and feel.</dd> |
| |
| <dt>Simplified configuration</dt> |
| |
| <dd>Many confusing directives have been simplified. The often |
| confusing <code>Port</code> and <code>BindAddress</code> directives |
| are gone; only the <code class="directive"><a href="./mod/mpm_common.html#listen">Listen</a></code> |
| directive is used for IP address binding; the <code class="directive"><a href="./mod/core.html#servername">ServerName</a></code> directive specifies the |
| server name and port number only for redirection and vhost |
| recognition.</dd> |
| |
| <dt>Native Windows NT Unicode Support</dt> |
| |
| <dd>Apache 2.0 on Windows NT now uses utf-8 for all filename |
| encodings. These directly translate to the underlying Unicode |
| file system, providing multilanguage support for all Windows |
| NT-based installations, including Windows 2000 and Windows XP. |
| <em>This support does not extend to Windows 95, 98 or ME, which |
| continue to use the machine's local codepage for filesystem |
| access.</em></dd> |
| |
| <dt>Regular Expression Library Updated</dt> |
| |
| <dd>Apache 2.0 includes the <a href="http://www.pcre.org/">Perl |
| Compatible Regular Expression Library</a> (PCRE). All regular |
| expression evaluation now uses the more powerful Perl 5 |
| syntax.</dd> |

| <h2><a name="module" id="module">Module Enhancements</a></h2> |
| |
| |
| <dl> |
| <dt><code class="module"><a href="./mod/mod_ssl.html">mod_ssl</a></code></dt> |
| |
| <dd>New module in Apache 2.0. This module is an interface |
| to the SSL/TLS encryption protocols provided by |
| OpenSSL.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_dav.html">mod_dav</a></code></dt> |
| |
| <dd>New module in Apache 2.0. This module implements the HTTP |
| Distributed Authoring and Versioning (DAV) specification for |
| posting and maintaining web content.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_deflate.html">mod_deflate</a></code></dt> |
| |
| <dd>New module in Apache 2.0. This module allows supporting |
| browsers to request that content be compressed before delivery, |
| saving network bandwidth.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_auth_ldap.html">mod_auth_ldap</a></code></dt> |
| |
| <dd>New module in Apache 2.0.41. This module allows an LDAP |
| database to be used to store credentials for HTTP Basic |
| Authentication. A companion module, <code class="module"><a href="./mod/mod_ldap.html">mod_ldap</a></code> |
| provides connection pooling and results caching.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_auth_digest.html">mod_auth_digest</a></code></dt> |
| |
| <dd>Includes additional support for session caching across |
| processes using shared memory.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_charset_lite.html">mod_charset_lite</a></code></dt> |
| |
| <dd>New module in Apache 2.0. This experimental module allows |
| for character set translation or recoding.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_file_cache.html">mod_file_cache</a></code></dt> |
| |
| <dd>New module in Apache 2.0. This module includes the |
| functionality of <code>mod_mmap_static</code> in Apache 1.3, |
| plus adds further caching abilities.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_headers.html">mod_headers</a></code></dt> |
| |
| <dd>This module is much more flexible in Apache 2.0. It can now |
| modify request headers used by <code class="module"><a href="./mod/mod_proxy.html">mod_proxy</a></code>, and |
| it can conditionally set response headers.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_proxy.html">mod_proxy</a></code></dt> |
| |
| <dd>The proxy module has been completely rewritten to take |
| advantage of the new filter infrastructure and to implement a |
| more reliable, HTTP/1.1 compliant proxy. In addition, new |
| <code class="directive"><a href="./mod/mod_proxy.html#proxy"><Proxy></a></code> |
| configuration sections provide more readable (and internally |
| faster) control of proxied sites; overloaded <code><Directory |
| "proxy:..."></code> configuration are not supported. The module |
| is now divided into specific protocol support modules including |
| <code>proxy_connect</code>, <code>proxy_ftp</code> and |
| <code>proxy_http</code>.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_negotiation.html">mod_negotiation</a></code></dt> |
| |
| <dd>A new <code class="directive"><a href="./mod/mod_negotiation.html#forcelanguagepriority">ForceLanguagePriority</a></code> directive can be used to assure that |
| the client receives a single document in all cases, rather than |
| NOT ACCEPTABLE or MULTIPLE CHOICES responses. In addition, the |
| negotiation and MultiViews algorithms have been cleaned up to |
| provide more consistent results and a new form of type map that |
| can include document content is provided.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_autoindex.html">mod_autoindex</a></code></dt> |
| |
| <dd>Autoindex'ed directory listings can now be configured to |
| use HTML tables for cleaner formatting, and allow finer-grained |
| control of sorting, including version-sorting, and wildcard |
| filtering of the directory listing.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_include.html">mod_include</a></code></dt> |
| |
| <dd>New directives allow the default start and end tags for SSI elements |
| to be changed and allow for error and time format configuration |
| to take place in the main configuration file rather than in the |
| SSI document. Results from regular expression parsing and grouping |
| (now based on Perl's regular expression syntax) can be retrieved |
| using <code class="module"><a href="./mod/mod_include.html">mod_include</a></code>'s variables <code>$0</code> |
| .. <code>$9</code>.</dd> |
| |
| <dt><code class="module"><a href="./mod/mod_auth_dbm.html">mod_auth_dbm</a></code></dt> |
| |
| <dd>Now supports multiple types of DBM-like databases using the |
| <code class="directive"><a href="./mod/mod_auth_dbm.html#authdbmtype">AuthDBMType</a></code> |
| directive.</dd> |
