- # many folks saw it. The simple approach to fixing it

-"""An HTTP handler for urllib2 that supports HTTP 1.1 and keepalive.
-
->>> import urllib2
->>> from keepalive import HTTPHandler
->>> keepalive_handler = HTTPHandler()
->>> opener = urllib2.build_opener(keepalive_handler)
->>> urllib2.install_opener(opener)
->>>
->>> fo = urllib2.urlopen('http://www.python.org')
-
-If a connection to a given host is requested, and all of the existing
-connections are still in use, another connection will be opened. If
-the handler tries to use an existing connection but it fails in some
-way, it will be closed and removed from the pool.
-
-To remove the handler, simply re-run build_opener with no arguments, and
-install that opener.
-
-You can explicitly close connections by using the close_connection()
-method of the returned file-like object (described below) or you can
-use the handler methods:
-
- close_connection(host)
- close_all()
- open_connections()
-
-NOTE: using the close_connection and close_all methods of the handler
-should be done with care when using multiple threads.
- * there is nothing that prevents another thread from creating new
- connections immediately after connections are closed
- * no checks are done to prevent in-use connections from being closed
-
->>> keepalive_handler.close_all()
-
-EXTRA ATTRIBUTES AND METHODS
-
- Upon a status of 200, the object returned has a few additional
- attributes and methods, which should not be used if you want to
- remain consistent with the normal urllib2-returned objects:
-
- close_connection() - close the connection to the host
- readlines() - you know, readlines()
- status - the return status (ie 404)
- reason - english translation of status (ie 'File not found')
-
- If you want the best of both worlds, use this inside an
- AttributeError-catching try:
-
- >>> try: status = fo.status
- >>> except AttributeError: status = None
-
- Unfortunately, these are ONLY there if status == 200, so it's not
- easy to distinguish between non-200 responses. The reason is that
- urllib2 tries to do clever things with error codes 301, 302, 401,
- and 407, and it wraps the object upon return.
-
- For python versions earlier than 2.4, you can avoid this fancy error
- handling by setting the module-level global HANDLE_ERRORS to zero.
- You see, prior to 2.4, it's the HTTP Handler's job to determine what
- to handle specially, and what to just pass up. HANDLE_ERRORS == 0
- means "pass everything up". In python 2.4, however, this job no
- longer belongs to the HTTP Handler and is now done by a NEW handler,
- HTTPErrorProcessor. Here's the bottom line:
-
- python version < 2.4
- HANDLE_ERRORS == 1 (default) pass up 200, treat the rest as
- errors
- HANDLE_ERRORS == 0 pass everything up, error processing is
- left to the calling code
- python version >= 2.4
- HANDLE_ERRORS == 1 pass up 200, treat the rest as errors
- HANDLE_ERRORS == 0 (default) pass everything up, let the
- other handlers (specifically,
- HTTPErrorProcessor) decide what to do
-
- In practice, setting the variable either way makes little difference
- in python 2.4, so for the most consistent behavior across versions,
- you probably just want to use the defaults, which will give you
- exceptions on errors.
