[Zope] Timeout on server when python script is running

[sguglia at arrows.it]

Hello everybody!

I have a python script running from a plone site..it takes a lot of time (1 
hour maybe more) but I need to run it just for data recovery if something 
goes wrong. after about 20 minutes a "Timeout on server" message pops up..

I tried and found where to change timeouts in zope.conf, but nothing changed. 
Wrong place? Please help, thanks!
