Before installing W3TC, if I typed in my domain.com (without www) it would automatically redirect to http://www.domain.com. Once activating W3TC, that redirect no longer works. If I deactivate W3TC, it works again.
With W3TC activated, if I clear all caches and try it, the first time the redirect works, but after that it doesn't. Is that normal? I know others who have W3TC and their redirect still works, so I'm confused. How do I fix this?
