response objects. The function is passed the response object and has
to return the same or a new one.
Example::
@app.route('/')
def index():
@after_this_request
def add_header(response):
response.headers['X-Foo'] = 'Parachute'
return response
return 'Hello World!'
This is more useful if a function other than the view function wants to
modify a response. For instance think of a decorator that wants to add
some headers without converting the return value into a response object.

request context. This is useful when working with greenlets. The moment
the function is decorated a copy of the request context is created and
then pushed when the function is called. The current session is also
included in the copied request context.
Example::
import gevent
from flask import copy_current_request_context
@app.route('/')
def index():
@copy_current_request_context
def do_some_work():
# do some work here, it can access flask.request or
# flask.session like you would otherwise in the view function.
...
gevent.spawn(do_some_work)
return 'Regular response'

AppContexta] The application context binds an application object implicitly
to the current thread or greenlet, similar to how the
:class:`RequestContext` binds request information. The application
context is also implicitly created if a request context is created
but the application is not on top of the individual application
context.

created at the beginning of the request and pushed to the
`_request_ctx_stack` and removed at the end of it. It will create the
URL adapter and request object for the WSGI environment provided.
Do not attempt to use this class directly, instead use
:meth:`~flask.Flask.test_request_context` and
:meth:`~flask.Flask.request_context` to create this object.
When the request context is popped, it will evaluate all the
functions registered on the application for teardown execution
(:meth:`~flask.Flask.teardown_request`).
The request context is automatically popped at the end of the request
for you. In debug mode the request context is kept around if
exceptions happen so that interactive debuggers have a chance to
introspect the data. With 0.4 this can also be forced for requests
that did not fail and outside of ``DEBUG`` mode. By setting
``'flask._preserve_context'`` to ``True`` on the WSGI environment the
context will not pop itself at the end of the request. This is used by
the :meth:`~flask.Flask.test_client` for example to implement the
deferred cleanup functionality.
You might find this helpful for unittests where you need the
information from the context local around for a little longer. Make
sure to properly :meth:`~werkzeug.LocalStack.pop` the stack yourself in
that situation, otherwise your unittests will leak memory.

This can be used to move a request context to a different greenlet.
Because the actual request object is the same this cannot be used to
move a request context to a different thread unless access to the
request object is locked.

.. versionchanged:: 1.1
The current session object is used instead of reloading the original
data. This prevents `flask.session` pointing to an out-of-date object.
