Hi!
Sorry, but I not understand it fully.
I thinking about that:
If I do this, only one interpreter created.
And this interpreter serve all of the requests.
So any concurrent requests are "need to pause" until the interpreter
getting free state, and ready to serve the next request.
Or I thinking wrong?
If not, that is making "slow" serving, or not?
Any question that if I must use cgi, can I use template system without
any problems? Rendering is need apache import? If yes, it is not working
in normal interpreter...
Thanks for your help:
