To re-iterate:

- Your suggested patch does nothing for nginx itself where the 
  upstream module infrastructure is used by the upstream module, 
  and c->data points to the request, so saving it will just waste 
  resources.  Your patch only makes sense for your module (which 
  is basically a hack by design).

- There is a proper way to do what you are trying to do, not 
  limited to your module.  You are free to use it, much like other 
  modules do.

Hope this helps.
