The Apache Group is proud to announce the twenty-eighth release of Apache 2.0. This is the second public beta of Apache 2.0. This release has been tested thoroughly and has been running the apache.org web site since Nov. 9, 2001.

Apache 2.0 offers numerous enhancements, improvements and performance boosts over the 1.3 code base. The most visible and noteworthy addition is the ability to run Apache in a hybrid thread/process mode on any platform that supports both threads and processes. This has been shown to improve the scalability of the Apache HTTPD server significantly on some versions of Unix in our testing. Apache 2.0 also includes support for filtered I/O. This allows modules to modify the output of other modules before it is sent to the client. Finally, we have included support for IPv6 on any platform that supports IPv6.

This version of Apache is known to work on many versions of Unix, BeOS, OS/2, and Windows. Because of many of the advancements in Apache 2.0, this release of Apache is expected to perform equally well on all supported platforms.

Apache has been the most popular web server on the Internet since April of 1996. The October 2001 WWW server site survey by Netcraft (http://www.netcraft.com/survey/) found that more web servers were using Apache than any other software running on more than 56% of the Internet web servers.

You can download Apache 2.0.28 from http://www.apache.org/dist/httpd/. For more information, please check out http://httpd.apache.org/.

Changes since the last public release

Known issues with this release

• There is a bug which can cause the response headers to be omitted when sending a negotiated ErrorDocument because the required filters were attached to the wrong request_rec. This can affect installations which enable authentication on / or /error, among others. A workaround is to comment out the ErrorDocument 401 directive in the default config file. A patch for this problem has already been committed to CVS and will be included in the next release. The patch is available at:

     
  http://www.apache.org/dist/httpd/patches/apply_to_2.0.28/errordoc.patch
  

• MacOSX users must use the darwin-specific tarball, which was built with a version of libtool that is compatible with that platform.
• The MacOSX/Darwin port currently does not support DSOs.
• On MacOSX/Darwin, "make" may generate many warning messages such as:

   
       /usr/bin/ld: warning multiple definitions of symbol _regcomp
      
  /Users/gregames/httpd-2_0_28/srclib/pcre/.libs/libpcre.al(pcreposix.lo)
            definition of _regcomp in section (__TEXT,__text)
       /usr/lib/libm.dylib(regcomp.o) definition of _regcomp/
  

  These messages may be ignored.
• On MacOSX/Darwin, Apache doesn't correctly handle the case- insensitive file system (HFS+), which can lead to access control problems.
• There is a known problem when ProxyPass is used in combination with mod_include; including a remote file from another remote file does not currently work.
• On BSDi, if you re-run configure, make will fail with messages like:

       "/usr/src/httpd-2_0_28/build/rules.mk, line 57: Need an operator".
  

  A workaround for this problem is to execute the following commands from the httpd-2_0_28 directory, after which make will work correctly:

          $ rm bsd_converted
          $ build/bsd_makefile
