Hmmm ... that certainly sounds like bad advice to me. But if you're working an a multi-process Apache model, you can't share database connections between different child processes. So either you have to be content with one connection per child process, or you have to switch Apache to only run in one process Chris Jackson wrote: >I've been reading this FAQ: > >http://www.modpython.org/FAQ/faqw.py?req=show&file=faq03.018.htp > >However, it doesn't answer my question of how to use one connection >accross multiple sessions. >It ends in saying: > >"My advice is to renew database connections, configs and everything >you have to load for a request every hit during development.
