``SimpleHTTPServer`` --- Simple HTTP request handler
****************************************************

Note: The ``SimpleHTTPServer`` module has been merged into ``http.server``
  in Python 3.0.  The *2to3* tool will automatically adapt imports
  when converting your sources to 3.0.

The ``SimpleHTTPServer`` module defines a single class,
``SimpleHTTPRequestHandler``, which is interface-compatible with
``BaseHTTPServer.BaseHTTPRequestHandler``.

The ``SimpleHTTPServer`` module defines the following class:

class SimpleHTTPServer.SimpleHTTPRequestHandler(request, client_address, server)

   This class serves files from the current directory and below,
   directly mapping the directory structure to HTTP requests.

   A lot of the work, such as parsing the request, is done by the base
   class ``BaseHTTPServer.BaseHTTPRequestHandler``.  This class
   implements the ``do_GET()`` and ``do_HEAD()`` functions.

   The following are defined as class-level attributes of
   ``SimpleHTTPRequestHandler``:

   server_version

   This will be ``"SimpleHTTP/" + __version__``, where ``__version__``
   is defined at the module level.

   extensions_map

      A dictionary mapping suffixes into MIME types. The default is
      signified by an empty string, and is considered to be
      ``application/octet-stream``. The mapping is used case-
      insensitively, and so should contain only lower-cased keys.

   The ``SimpleHTTPRequestHandler`` class defines the following
   methods:

   do_HEAD()

      This method serves the ``'HEAD'`` request type: it sends the
      headers it would send for the equivalent ``GET`` request. See
      the ``do_GET()`` method for a more complete explanation of the
      possible headers.

   do_GET()

      The request is mapped to a local file by interpreting the
      request as a path relative to the current working directory.

      If the request was mapped to a directory, the directory is
      checked for a file named ``index.html`` or ``index.htm`` (in
      that order). If found, the file's contents are returned;
      otherwise a directory listing is generated by calling the
      ``list_directory()`` method. This method uses ``os.listdir()``
      to scan the directory, and returns a ``404`` error response if
      the ``listdir()`` fails.

      If the request was mapped to a file, it is opened and the
      contents are returned.  Any ``IOError`` exception in opening the
      requested file is mapped to a ``404``, ``'File not found'``
      error. Otherwise, the content type is guessed by calling the
      ``guess_type()`` method, which in turn uses the *extensions_map*
      variable.

      A ``'Content-type:'`` header with the guessed content type is
      output, followed by a ``'Content-Length:'`` header with the
      file's size and a ``'Last-Modified:'`` header with the file's
      modification time.

      Then follows a blank line signifying the end of the headers, and
      then the contents of the file are output. If the file's MIME
      type starts with ``text/`` the file is opened in text mode;
      otherwise binary mode is used.

      For example usage, see the implementation of the ``test()``
      function.

      New in version 2.5: The ``'Last-Modified'`` header.
