BernieC has asked for the wisdom of the Perl Monks concerning the following question:

I know this is a dumb question but I'm lost in a maze of twisty passages going back and forth between LWP::UserAgent and HTTP::Request::Common. I have a very simple question. I need to send a POST with the body being JSON data and I understand {I think} that to make that play nice with the server I should have a "content-type: application/json" header ... it should be trivial but I can't figure out where to stick that information in the $ua->POST() call. I must be missing something obvious.
