Get the request_body in a handler

[nooske]

Hi, I'm trying to make a module that will get the body of http requests and
print it in my log. 

I tried to access the variable r->request_body (r is a ngx_http_request_t *)
and it's always empty. 
I also know that the content is saved in a temp file, so maybe I can get it
but I don't know also how to find the name of this temp file.

Do you have any idea ? 

Thank you :)
