Permanent database connection in fastcgi

Question

I am moving the application from php to fastcgi (c). My host works with apache.

Since the fastcgi application will run in a loop, I can open the mysql connection and leave it open for all incoming requests. Is this recommended?

I think I read about an equal number of opinions saying that a connection is much more expensive than a request, and it should be constant, and on the other hand, people who claim that an open connection is resource-intensive should be closed every time.

Which one is correct in my context?
