Hi, Brady,

Any comments on this?

I think cache validation should happen every time, as Alexey pointed out.
(I'd exclude the validations at screen/print switching time, though.
But this is a different story.)

I could understand limiting validation to only the first load for a page,
trading correctness for the performance gain, I guess.

I don't understand the current behavior, though: validation for the first
and the second load, no validation there after. What is the rationale
behind the current behavior?
