+
+    Using ``__setitem__`` syntax overwrites fields that compare equal

+'''SSL with SNI_-support for Python 2. Follow these instructions if you would
+like to verify SSL certificates in Python 2. Note, the default libraries do
+*not* do certificate checking; you need to do additional work to validate
+certificates yourself.
+
+This needs the following packages installed:
+
+* pyOpenSSL (tested with 0.13)
+* ndg-httpsclient (tested with 0.3.2)
+* pyasn1 (tested with 0.1.6)
+
+You can install them with the following command:
+
+    pip install pyopenssl ndg-httpsclient pyasn1
+
+To activate certificate checking, call
+:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
+before you begin making HTTP requests. This can be done in a ``sitecustomize``
+module, or at any other time before your application begins using ``urllib3``,
+like this::
+
+    try:
+        import urllib3.contrib.pyopenssl
+        urllib3.contrib.pyopenssl.inject_into_urllib3()
+    except ImportError:
+        pass
+
+Now you can use :mod:`urllib3` as you normally would, and it will support SNI
+when the required modules are installed.
+
+Activating this module also has the positive side effect of disabling SSL/TLS
+encryption in Python 2 (see `CRIME attack`_).
+
+If you want to configure the default list of supported cipher suites, you can
+set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

+
+        Many factors can affect the total amount of time for urllib3 to return

+        timeout specified on the socket. Other factors that can affect total
+        request time include high CPU load, high swap, the program running at a
+        low priority level, or other behaviors. The observed running time for
+        urllib3 to return a response may be greater than the value passed to
+        `total`.
+
+        In addition, the read and total timeouts only measure the time between
+        read operations on the socket connecting the client and the server,
+        not the total amount of time for the request to return a complete
+        response. For most requests, the timeout is raised because the server
+        has not sent the first byte in the specified time. This is not always
+        the case; if a server streams one byte every fifteen seconds, a timeout
+        of 20 seconds will not ever trigger, even though the request will
+        take several minutes to complete.
+
+        If your goal is to cut off any request after a set amount of wall clock
+        time, consider having a second "watcher" thread to cut off a slow
+        request.
