Http PUT to a JSON store

Http PUT to a JSON store

What is the LiveCode equivalent of the following JavaScript code snippet?
var req = new XMLHttpRequest();
req.open("PUT", theURLoftheNoSQLstore, false);
req.setRequestHeader('Content-Type', mimeType);
req.send(theJSONobjString);
The parameters have been defined as
theJSONobj = {};
theJSONobj["aKey"] = "aValue";
theJSONobj["anotherKey"] = 123;
theJSONobj["note"] = "some note about the issue";
theJSONobjString = JSON.stringify(theJSONobj);
theURLoftheNoSQLstore ="http://localhost:5984/thedb/thekey"
mimeType="application/json";
Note
Setting the mimeType has been added for completeness. However for posting
to the JSON store it is not necessary as that is the default in this case
(couchDB).
