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 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's configuration system more similar to
that of other packages.
Multiprotocol Support
Apache 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 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 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 server.
IPv6 Support
On systems where IPv6 is supported by the underlying Apache Portable
Runtime library, Apache gets IPv6 listening sockets by default.
Additionally, the Listen, NameVirtualHost, and VirtualHost directives
support IPv6 numeric address strings (e.g., "Listen [fe80::1]:8080").
Filtering
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 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 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
Module Enhancements
mod_ssl
New module in Apache 2.0. This module is an interface to the SSL/TLS
encryption protocols provided by OpenSSL.
mod_dav
New module in Apache 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 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 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 2.0. This experimental module allows for
character set translation or recoding.
mod_file_cache
New module in Apache 2.0. This module includes the functionality of
mod_mmap_static in Apache 1.3, plus adds further caching abilities.
mod_headers
This module is much more flexible in Apache 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.
