Here is an example how to set a Request Header in a JQuery Ajax Call:

$.ajax({

type:"POST",

beforeSend: function (request)

{

request.setRequestHeader("Authority", authorizationToken);

url: "entities",

data: "json=" + escape(JSON.stringify(createRequestObject)),

processData: false,

success: function(msg) {

$("#results").append("The result =" + StringifyPretty(msg));

}

});

in another example,

$.ajax({

url: "/test",

headers: {"X-Test-Header": "test-value"}

});
