How to Grab arguments in POST request?

In nginx 0.6.37, is there any way at all to get the arguments of a POST
request? I’ve seen that this doesn’t work with static files, but is
there any way to structure the POST request such that I can grab the
arguments in my nginx server? Thanks!

Also wondering, in the new nginx dev versions with the new built-in
caching methods, is there any way to get POST arguments there?
