This is useful to modify 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. .. versionadded:: 0.9 (RRt_after_request_functionstappend(tf((sO/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/flask/ctx.pytafter_this_request+sc€sOtj}|dkr$tdƒ‚n|jƒ‰‡‡fd†}t|ˆƒS(sàA helper function that decorates a function to retain the current 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.

It is 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. cC€sÝ||_|dkr'|j|ƒ}n||_|j|jƒ|_d|_d|_g|_t |_ d|_ g|_ |j ƒ|jj}|dk rÙ|jj|ƒ}|dk rÙt|ƒrÙt|j_qÙndS(N(RRt request_classtrequestR(R)tflashestsessiont_implicit_app_ctx_stacktFalset preservedt_preserved_excRt match_requestt blueprintt blueprintsR RtTruet_is_old_module(R RtenvironR>RFtbp((sO/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/flask/ctx.pyR-Ûs"            cC€s tjjS(N(RRR+(R ((sO/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/flask/ctx.pyt_get_gscC€s|tj_dS(N(RRR+(R tvalue((sO/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/flask/ctx.pyt_set_gscC€s%|j|jd|jjd|jƒS(srCreates a copy of this request context with the same request object.
