There are many ways - you can use libCURL to make the request, or you can revisit the two
code examples I gave you.  One was from my memory, then realizing I had forgotten a lot of
it, I scraped some code from a functional module.  Did you notice both examples?  The bottom
one was just to point you in the right direction.  I have simplified the other one that I
had scraped from a functional module, and stuffed it into a fresh module generated by "apxs
-g -n subrequest", and it compiled quite nicely.  The diff :

I am presuming you copied and pasted my over simplified example at the bottom of my response
rather than using the top code section.
