this does not work, no cookie is set. anything wrong with this?
def before_request():
r = flask.make_response()
r.set_cookie('test',value='test')

Since you don't know the response until it comes from the view you need to do that in the after_request function: @app.after_request def after_request(response): response.set_cookie('test', value='test') return response Regards, Armin

Correct. However there are many ways you can still make it works. For example this snippet shows how you can build per-request after request handlers: http://flask.pocoo.org/snippets/53/ With that you can issue a deferred call in a before_request handler: @app.before_request def before_request(): @after_this_request def attach_cookie(response): response.set_cookie('foo', 'bar') return response Regards, Armin

OK, is this also true for response.headers.add? ie can i add headers only from after_request? thanks
I *think* Armin may have misread your 2nd message Kevin. You can in fact set cookies in the url handler if that works better for you. You can headers in after_request or url handlers. It is like this, if you have the response object ... and it is not going to be overwritten ... then you can set headers and cookies.

You just use make_response to get a response object and then set the same way as in the other examples. Let me know if you need more detail. - sent from my android phone On Aug 15, 2011 8:02 PM, "kevin" <kevincastiglione@gmail.com> wrote: > On Mon, Aug 15, 2011 at 1:01 PM, Jay Baker <jbaker.work@gmail.com> wrote: > >> I *think* Armin may have misread your 2nd message Kevin.

so that is what i did in before_request and it did not work. but that would
work in app handler?
this does not work, no cookie is set. anything wrong with this?
def before_request():
r = flask.make_response()
r.set_cookie('test',value='test')

If you look at what you have below, ask yourself, what is that response object? What happens to it when the url handler gets called? In before_request, you have no valid response. It is "setting up" the request. Anyway, the easiest way to investigate that is to just try it and look at the results. I suggest looking at the source of render_template or whatever else you may be using in the url handler to further understand the lifestyle of.the response object. - sent from my android phone On Aug 15, 2011 9:56 PM, "kevin" <kevincastiglione@gmail.com> wrote: > so that is what i did in before_request and it did not work. but that would > work in app handler? > > > > this does not work, no cookie is set. anything wrong with this? > > def before_request(): > r = flask.make_response() > r.set_cookie('test',value='test') > > On Mon, Aug 15, 2011 at 6:09 PM, Jay Baker <jbaker.work@gmail.com> wrote: > >> You just use make_response to get a response object and then set the same >> way as in the other examples.

You are not returning the response you created in the view, that response is never send to the client and therefore no cookie is set.
