Prerequisite for vs. "prerequisite to"?

Question

When is it appropriate to use "prerequisite for" instead of "prerequisite to"? Does it depend on context, or is it a matter of style?I googled the two phrases and found 4.5 million hits for "prerequisite for" and 3 million for "prerequisite to".

Answer 1

Then the "fors" have it. I use "for" and so do all the educated people I know.
