:mod:`SimpleHTTPServer` --- Simple HTTP request handler

.. module:: SimpleHTTPServer
 :synopsis: This module provides a basic request handler for HTTP servers.

.. sectionauthor:: Moshe Zadka <moshez@zadka.site.co.il>

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

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

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 :class:`BaseHTTPServer.BaseHTTPRequestHandler`. This class implements the :func:`do_GET` and :func:`do_HEAD` functions.

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

.. attribute:: server_version

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

.. attribute:: 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 :class:`SimpleHTTPRequestHandler` class defines the following methods:

.. method:: do_HEAD()

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

.. method:: 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 :meth:`list_directory` method. This method uses
 :func:`os.listdir` to scan the directory, and returns a ``404`` error
 response if the :func:`listdir` fails.

 If the request was mapped to a file, it is opened and the contents are
 returned. Any :exc:`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 :meth:`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 :func:`test` function.
