I'm making ajax POST request from javascript function:

function UpdateMetrics() {

   $.ajax({

              type: POST,

              url: MyHandler.ashx?Param1=value1,

              data: {},

              contentType: text/json; charset=utf-8,

              dataType: text,

              success: function (msg) {

                  var jsonUpdatedData = msg;

                  ...

              }

          });

}

From my handler, I'm sending json string with:

context.Response.write(json);

I think I'll get it in msg.

I also want to send other string (count). So I'm trying to use header info along with json data. So I added this line:

context.Response.Headers.Add(MaxCount,Convert.ToString(tempList.Count)); 

If this is right way to do it, how can I access it in my success function?
