How does nginx caching handle multiple cache control headers sent from a

I had a situation where I was sending both expires and cache-control and
it seemed that the order in which they were sent controlled.  I solved
that problem by ignoring the expires header.  

I thought I recalled that x-accel-expires would override any other
headers regardless of order, but that doesn't seem to be the case.

Is there a priority, or does order control?
