| <h1 align="CENTER">Overview of new features</h1> |
| |
| <h2>API Changes</h2> |
| A few changes to the Apache API were made for 1.1. It is |
| possible that some third-party modules will no longer work with |
| 1.1, though we have made every effort to provide |
| backwards-compatibility. If you encounter a module that does |
| not work with 1.1, please <a |
| href="http://httpd.apache.org/bug_report.html">let us know</a>. |
| |
| |
| <h2>New Features with Apache 1.1</h2> |
| |
| <p>New features with this release, as extensions of the Apache |
| functionality (see also more detailed <code>CHANGES</code> file |
| in the source directory.) Because the core code has changed so |
| significantly, there are certain liberties that earlier |
| versions of Apache (and the NCSA daemon) took that recent |
| Apache versions are pickier about - please check the <a |
| href="misc/compat_notes.html">compatibility notes</a> if you |
| have any problems.</p> |
| <hr /> |
| |
| <p>In addition to a number of bug fixes and internal |
| performance enhancements, <a |
| href="http://www.apache.org/dist/httpd/">Apache 1.1</a> has the |
| following specific new user features:</p> |
| |
| <ul> |
| <li><strong><a href="keepalive.html">Support for Keep-Alive |
| Persistent Connections</a></strong><br /> |
| Apache now has (optional) support for persistent |
| connections, as defined by the HTTP/1.1 draft. This protocol, |
| supported by a number of current HTTP servers and browsers |
| (including Netscape Navigator 2.0) has been shown to increase |
| speed of document transfer by up to 50% in certain |
| cases.</li> |
| |
| <li><strong><a href="vhosts/">New non-IP |
| Intensive-VirtualHost Support</a></strong><br /> |
| Apache's support for virtual hosts has been enhanced to be |
| able to use information sent by some new Web browsers to |
| determine the server being accessed, without requiring an |
| additional IP address for each host.</li> |
| |
| <li><strong><a href="bind.html">Listen to Multiple Addresses |
| and Ports</a></strong><br /> |
| Using the new <code>Listen</code> directive, Apache can |
| listen to more than one port and IP address, using the same |
| configuration set.</li> |
| |
| <li><strong><a href="mod/mod_status.html">Status |
| Module</a></strong><br /> |
| Apache now contains a module that gives the web-master |
| accurate, up-to-date information about the server's status |
| and its resource consumption. It also gives the current state |
| of each server process including the current URL being |
| processed. For an example, check out <a |
| href="http://www.apache.org/server-status">the status of the |
| www.apache.org server</a>.</li> |
| |
| <li><strong><a href="mod/mod_info.html">Server Information |
| Module</a></strong> This module gives a plethora of |
| information about the other modules installed, their |
| directives, and their configurations. It is extremely helpful |
| in debugging configuration problems. For an example, check |
| out <a href="http://www.apache.org/server-info">information |
| about the www.apache.org server</a>.</li> |
| |
| <li><strong><a href="mod/mod_proxy.html">Experimental Caching |
| Proxy Server</a></strong><br /> |
| Apache can now act as an HTTP proxy server, allowing clients |
| behind firewalls to use the server to access the outside |
| world. In addition, it can cache documents it proxies, |
| speeding up access to frequently requested documents.</li> |
| |
| <li><strong><a href="location.html">URL-based Access |
| Protection</a></strong><br /> |
| In addition to access checking and authorization by filename |
| (with <code><a |
| href="mod/core.html#directory"><Directory></a></code>), |
| the new <code><Location></code> directive allows |
| protection by URL.</li> |
| |
| <li><strong><a href="mod/mod_actions.html">Filetype-based |
| Script "Actions"</a></strong><br /> |
| You can now run CGI scripts whenever a file of a certain |
| type is requested. This makes it much easier to execute |
| scripts that process files. In addition, you can use the new |
| <a href="mod/mod_actions.html#script">Script</a> directive to |
| enable scripts for files called with HTTP methods Apache does |
| not natively support.</li> |
| |
| <li><strong><a href="handler.html">New "Handler" |
| Directives</a></strong><br /> |
| The new <code>AddHandler</code> and <code>SetHandler</code> |
| directive allows "handlers" to be defined for filename |
| extensions or directories. These handlers, which can either |
| be built into Apache or added with the <a |
| href="mod/mod_actions.html">Action</a> directive, extend |
| Apache's range of usability, and almost entirely remove the |
| "magic" media types.</li> |
| |
| <li><strong><a href="mod/mod_env.html">Customizable CGI |
| Environment Variables</a></strong><br /> |
| New <code>PassEnv</code> and <code>SetEnv</code> directives |
| allow you to modify the environment variables passed to CGI |
| scripts.</li> |
| |
| <li><strong><a href="mod/mod_cern_meta.html">CERN Metafile |
| Support</a></strong><br /> |
| Now emulates the CERN httpd's support for metafiles |
| containing additional HTTP headers to be supplied with a |
| document.</li> |
| |
| <li><strong><a href="mod/mod_imap.html">Improved Imagemap |
| Support</a></strong><br /> |
| The internal imagemap handling code has been rewritten and |
| reorganized, adding new handling of default, base and |
| relative URLs, and support for creating non-graphical menus |
| for use with clients that do not support imagemaps.</li> |
| |
| <li><strong><a href="mod/mod_userdir.html">Improved UserDir |
| Directive</a></strong><br /> |
| Now supports the ability to point user's files (as specified |
| by URLs beginning with the "<code>~</code>" character) at |
| directories other than those specified by the Unix password |
| file.</li> |
| |
| <li><strong>Minimal DNS Now Runtime Option</strong><br /> |
| New <code>HostnameLookups</code> server configuration |
| directive can be used to turn <code>On</code> or |
| <code>Off</code> DNS lookups. This supersedes the |
| -DMINIMAL_DNS compile-time configuration option. This option |
| can be set per-directory.</li> |
| |
| <li><strong>IdentityCheck Now Per-Directory |
| Option</strong><br /> |
| The <code>IdentityCheck</code> directive, which controls the |
| use of ident to check the remote user name, can now be set |
| per directory. The ident support is also RFC |
| 1413-compliant.</li> |
| |
| <li><strong>Redirect Now Usable in <code>.htaccess</code> |
| Files</strong><br /> |
| The <a |
| href="mod/mod_alias.html#redirect"><code>Redirect</code></a> |
| directive can now be used in <code>.htaccess</code> files |
| when the <code>FileInfo</code> directive has been set on. |
| This allows users to redirect parts of their directories |
| without requiring CGI scripts</li> |
| |
| <li><strong>ErrorDocument Now Usable in |
| <code>.htaccess</code> Files</strong><br /> |
| The <a |
| href="custom-error.html"><code>ErrorDocument</code></a> |
| directive can now be used in <code>.htaccess</code> files |
| when the <code>FileInfo</code> directive has been set on. |
| This allows users to have different error messages for |
| different sections of a site.</li> |
| |
| <li><strong><code>ForceType</code> Directive</strong><br /> |
| This new directive, in <code><Directory></code> |
| sections or .htaccess files, allows you to override the |
| filename extensions and force a single content type. |
| (<em>e.g.</em>, <code>ForceType |
| application/octet-stream</code>)</li> |
| |
| <li><strong>File Owner Available to Included CGI |
| Scripts</strong><br /> |
| Server-side includes that call CGI scripts will now set a |
| <code>USER_NAME</code> environment variable that contains the |
| owner of the file which included it.</li> |
| |
| <li><strong>Improved Icons</strong><br /> |
| Thanks to <a href="mailto:kevinh@eit.com">Kevin Hughes</a>, |
| Apache's nifty color GIF icons for directory listings have |
| been updated. In addition, the <a |
| href="../apache_pb.gif">Powered by Apache</a> |
| (<code>apache_pb.gif</code>) logo has been included.</li> |
| </ul> |
| <hr /> |
| |
| <h3>New Authentication Modules</h3> |
| |
| <p><strong>Note:</strong> These modules are not compiled into |
| the server by default, as they require special support on the |
| host system. They must be enabled specifically in the |
| <code>Configuration</code> file.</p> |
| |
| <ul> |
| <li><strong><a href="mod/mod_auth_anon.html">Anonymous HTTP |
| Logins</a></strong><br /> |
| New options allow you to allow, using Basic HTTP |
| Authentication, anonymous logins, like those of FTP. This |
| allows you to collect email addresses of people accessing |
| your site.</li> |
| |
| <li><strong><a href="mod/mod_digest.html">Support for Digest |
| Authentication</a></strong><br /> |
| Apache now supports digest authentication using RSA MD5 |
| encryption. When used with a supporting web browser, this |
| provides a more secure alternative to Basic |
| authentication.</li> |
| |
| <li><strong><a href="mod/mod_auth_db.html">Support for Unix |
| DB Authentication</a></strong> - |
| <code>mod_auth_db.c</code><br /> |
| In addition to <a href="mod/mod_auth_dbm.html">DBM</a> |
| support, Apache now contains optional support for Berkeley DB |
| databases.</li> |
| |
| <li><strong>mSQL Database Authentication</strong> - |
| <code>mod_auth_msql.html</code><br /> |
| Support for the use of mSQL databases for user |
| authentication via HTTP is now supported.</li> |
| </ul> |
| <hr /> |
| |
| <h3>OS/2 Support</h3> |
| |
| <p>Apache now includes support for OS/2, thanks to <a |
| href="http://www.slink.com/ApacheOS2/">Softlink |
| Services</a>.</p> |
