Subrequests were originally developed to for the SSI include 
command, and they are expected to return content of a particular 
resource - that is, they are GET.

If you want them to act differently, you can modify the method 
after a subrequest is created and/or use the NGX_HTTP_SUBREQUEST_CLONE 
flag.
