Developed web application where making ajax call to PI Web API as below. PI Web API configuration is set to basic authentication, hence I am passing credentials as required. 


function MakeAjaxRequest(type, url, SuccessCallBack, data) {
        type: type,
        url: url,
        cache: false,
        async: true,
        data: data,
        contentType: "application/json",
        beforeSend: function (xhr) {
            xhr.setRequestHeader('Authorization', make_base_auth(username, password));
        success: SuccessCallBack,
        error: (function (error, variable) {
            alert('There was an error with the request');


The issue is, when I run application for the first time, will be encountering access denied issue as show below. But if I run application after connecting to base PI web API (https://server/piwebapi/) by providing credentials in browser, it will works fine.
