Unable to set headers with Async http network.request - was this ever resolved?

I have found a post which I am unable to post a comment on (maybe it is too old?):

http://web-c3.anscamobile.com/forum/2011/02/09/unable-set-headers-async-http-networkrequest

I have exactly the same problem that the author of the post explains. Using Wireshark shows that my “POST” requests Content-Type is “application/x-www-form-urlencoded” even though I explicitly set it to “application/json” prior to making the request. That post had 2 replies from Ansca staff, but neither actually addressed the author’s problem.

My previous post explains how (I believe) this is causing me problems getting LinkedIn integrated with our Corona app:

I need to send json data to their API, and this is the last hurdle to overcome. As I’ve said before, once I have it working I’ll tidy up my project and provide a working sample project for everyone to use in future.
