Here's what I wanted to do:
1) I wanted to write a Nginx location handler for example "/mylocation"
which when invoked should call another program to get the response.
2) The other external program provides a client library where we can
3) The external program will call the callback when the data is available.
I wanted to know if I am using an external library and one of the external
API is asking for registering callback, how i can achieve this in Nginx.
I cannot give any function from my handler, as that is called internally by
the nginx Core.
Please guide me how I can register a callback inside Nginx which will be
called by the external program.
