Do you really want sessions or real globals? That kind of thing can
be a real bottleneck.
Here's a real simple example of something you could do if you really
wanted to:
import web
def add_global_hook():
g = web.storage({"counter": 0})
def _wrapper(handler):
web.ctx.globals = g
return handler()
return _wrapper
class Hello:
def GET(self):
web.ctx.globals.counter += 1
return "<h1>Counter: %d</h1>" % web.ctx.globals.counter
if __name__ == '__main__':
urls = ("/", "Hello")
app = web.application(urls, globals())
app.add_processor(add_global_hook())
app.run()
Note that it wouldn't work right in situations where requests are
handled in different actual processes (mod_python with a forking
MPM, forking FastCGI/SCGI handler, etc). Threaded will work fine.
