[Freeswitch-users] mod_curl setting content type header

Hi, Is there a way to set the Content-Type header when using mod_curl in a Lua script? Using curl on the command line I can do the following: curl -H "Content-Type: application/json" -H "Accept: application/json" -X POST -d '{"field1":"val1","field2":"val2"}' http://mydomain.com/ And in a Lua script I can do the following: local my_json = "{\"field1\":\"val1\",\"field2\":\"val2\"}" api = freeswitch.API() response_data = api:execute("curl", "http://mydomain.com/ post" .. my_json) But I don't see a way in the freeswitch API to set the Content-Type header in the above script. Appreciate any help or insight that can be offered. Thanks. Jeff
