This document describes some of the major changes between the + 1.3 and 2.0 versions of the Apache HTTP Server.

Core Enhancements

+ + +
+
Unix Threading
+ +
On Unix systems with POSIX threads support, Apache httpd can + now run in a hybrid multiprocess, multithreaded mode. This + improves scalability for many, but not all configurations.
+ +
New Build System
+ +
The build system has been rewritten from scratch to be + based on autoconf and libtool. + This makes Apache httpd's configuration system more similar to + that of other packages.
+ +
Multiprotocol Support
+ +
Apache HTTP Server now has some of the infrastructure in place to + support serving multiple protocols. mod_echo has + been written as an example.
+ +
Better support for non-Unix + platforms
+ +
Apache HTTP Server 2.0 is faster and more stable on non-Unix + platforms such as BeOS, OS/2, and Windows. With the + introduction of platform-specific multi-processing modules (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.
+ +
New Apache httpd API
+ +
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 HTTP Server.
+ +
IPv6 Support
+ +
On systems where IPv6 is supported by the underlying + Apache Portable Runtime library, Apache httpd gets IPv6 listening + sockets by default. Additionally, the Listen, NameVirtualHost, and VirtualHost directives support + IPv6 numeric address strings (e.g., "Listen + [2001:db8::1]:8080").
+ +
Filtering
+ +
Apache httpd 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 + INCLUDES filter in mod_include. The + module mod_ext_filter allows external programs to + act as filters in much the same way that CGI programs can act as + handlers.
+ +
Multilanguage Error Responses
+ +
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.
+ +
Simplified configuration
+ +
Many confusing directives have been simplified. The often + confusing Port and BindAddress directives + are gone; only the Listen + directive is used for IP address binding; the ServerName directive specifies the + server name and port number only for redirection and vhost + recognition.
+ +
Native Windows NT Unicode Support
+ +
Apache httpd 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. + This support does not extend to Windows 95, 98 or ME, which + continue to use the machine's local codepage for filesystem + access.
+ +
Regular Expression Library Updated
+ +
Apache httpd 2.0 includes the Perl + Compatible Regular Expression Library (PCRE). All regular + expression evaluation now uses the more powerful Perl 5 + syntax.

Module Enhancements

+ + +
+
mod_ssl
+ +
New module in Apache httpd 2.0. This module is an interface + to the SSL/TLS encryption protocols provided by + OpenSSL.
+ +
mod_dav
+ +
New module in Apache httpd 2.0. This module implements the HTTP + Distributed Authoring and Versioning (DAV) specification for + posting and maintaining web content.
+ +
mod_deflate
+ +
New module in Apache httpd 2.0. This module allows supporting + browsers to request that content be compressed before delivery, + saving network bandwidth.
+ +
mod_auth_ldap
+ +
New module in Apache httpd 2.0.41. This module allows an LDAP + database to be used to store credentials for HTTP Basic + Authentication. A companion module, mod_ldap + provides connection pooling and results caching.
+ +
mod_auth_digest
+ +
Includes additional support for session caching across + processes using shared memory.
+ +
mod_charset_lite
+ +
New module in Apache httpd 2.0. This experimental module allows + for character set translation or recoding.
+ +
mod_file_cache
+ +
New module in Apache httpd 2.0. This module includes the + functionality of mod_mmap_static in Apache HTTP + Server version 1.3, plus adds further caching abilities.
+ +
mod_headers
+ +
This module is much more flexible in Apache httpd 2.0. It can now + modify request headers used by mod_proxy, and + it can conditionally set response headers.
+ +
mod_proxy
+ +
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 + <Proxy> + configuration sections provide more readable (and internally + faster) control of proxied sites; overloaded <Directory + "proxy:..."> configuration are not supported. The module + is now divided into specific protocol support modules including + proxy_connect, proxy_ftp and + proxy_http.
+ +
mod_negotiation
+ +
A new ForceLanguagePriority 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.
+ +
mod_autoindex
+ +
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.
+ +
mod_include
+ +
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 mod_include's variables $0 + .. $9.
+ +
mod_auth_dbm
+ +
Now supports multiple types of DBM-like databases using the + AuthDBMType directive.
+ +
