      Some non-compatible changes were made to the Apache API in order to deal with HTTP/1.1 compatibility. It is possible that some modules will no longer work (specifically, those that process input using the POST or PUT methods). If you encounter a module that does not work, please contact the author. A programmer's note on the subject is available.
New features with this release, as extensions of the Apache functionality. 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 compatibility notes if you have any problems.
In addition to a number of bug fixes and internal performance enhancements, Apache 1.2 has the following specific new user features:
<Files>
      section allows directives to be enabled based on full
      filename, not just directory and URL. In addition,
      <Files> sections can appear in
      .htaccess files. <Files>,
      along with <Directory>
      and <Location>,
      can also now be based on regular expressions, not just simple
      prefix matching.User-Agent string of the browser. Combined with
      XSSI, this allows you to
      write browser-based conditional HTML documents.mod_rewrite module is now
      included. This module can provide powerful URL mapping, using
      regular expressions. There's nothing this module can't
      do!mod_log_config included with
      earlier versions of Apache is now standard, and has been
      enhanced to allow logging of much more detail about the
      transaction, and can be used to open more than one log file at once
      (each of which can have a different log format). If you have
      Apache write any logs to a directory which is writable by
      anyone other than the user that starts the server, see the security tips document to
      be sure you aren't putting the security of your server at
      risk.mod_cookies included with previous versions
      of Apache has been renamed mod_usertrack, to
      more accurately reflect its function (some people
      inadvertently thought it enabled cookie support in Apache,
      which is not true - Apache supports the use of cookies
      directly). It is also now possible to disable the generation
      of cookies, even when the cookie module is compiled in. Also,
      an expiry time can be set on the cookies.ScriptLog allows you to now set up a log that
      records all input and output to failed CGI scripts. This
      includes environment variables, input headers, POST data,
      output, and more. This makes CGI scripts much easier to
      debug.Options directive can now add or remove
      options from those currently in force, rather than always
      replacing them.-h command-line option now lists all the
      available directives.mod_headers module can be used to
      set custom headers in the HTTP response. It can append to
      existing headers, replace them, or remove headers from the
      response.<IfModule> section allows
      directives to be enabled only if a given module is loaded
      into the server.Satisfy allows for more flexible access control
      configurations.Satisfy, MaxKeepAliveRequests,
      RedirectPermanent
      and RedirectTemp,
      directives, and the following directives are now
      syntax-compatible with NCSA: AuthUserFile, AuthGroupFile, AuthDigestFile,
      KeepAlive and KeepAliveTimeout.
