Context: Imagine that you have a standard CherryPy hello word app:
def index(self):
return \"Hello world!\"
index.exposed = True
The "global threading aware queue" is called Queue.Queue. I just added a recipe for this at http://tools.cherrypy.org/wiki/BackgroundTaskQueue
As i was looking for this and it's now outdated, i found it useful to provide the correct (2012ish) answer. Simply add this at the beginning of the function that handles your url :
cherrypy.request.hooks.attach('on_end_request', mycallbackfunction)
There's more infos on hooks in the documentation but it's not very clear to me.
An on_end_request custom tool may be what you want.
