Nginx Proxy/FastCGI Caching X-Accel-Expires 0 or Off ?

So in order for my web application to tell Nginx not to cache a page what
header response should I be sending ?

X-Accel-Expires: 0
X-Accel-Expires: Off

I read here it should be "OFF"

But it does not mention if numeric value "0" has the same effect Nor does it
mention if the "off" value is case sensitive or not.

I am hoping case sensitivity does not matter.
