    XMLHttpRequest supported?


    I am trying to build an app which will need to use the XMLhttpRequest class to support AJAX..
    I am getting a message " the class XMLHttpRequest is not found". This leads me to question whether it is supported in Windows 10.
    I am using the latest release of Windows 10 (AU) and am testing with Wampserver 3 using NetBeans as an IDE.
    In an example of AJAX and JS with PHP in the server I have detected that after the JS statement
    var xmlhttp = new XMLHttpRequest();
    there is no xmlhttprequest object instantiated.

    Hence the question is XMLHttpRequest supported in Win10?

    :)

  2. Error 0x2efd in XMLHttpRequests crashes Hosted Web UWP App

    Hi,

    i have a crashing UWP App, that crashes when used Offline. It is a simple Web Hosted App that uses a remote StartPage.

    When starting offline the page loads from appcache, but then stops because of an exception in wwahost.exe.

    Windows Version is 1607 - 14393.693

    UWP App - Target Version is 10.0.14393.0

    Visual Studio 14.0.25431.01 Update 3

    I further investigated the problem and found out that it is related to XMLHttpRequests.

    if the XMLHttpRequests fails the App crashes. The Javascript console shows the following error:

    SCRIPT7002: XMLHttpRequest: Netzwerkfehler 0x2efd, Der Vorgang konnte aufgrund des folgenden Fehlers nicht fortgesetzt werden: 00002efd.

    If i handle the error in the onerror callback of the XMLHTTPRequest my code gets called after the above error and the App still crashes.

    if i override the open call of the XMLHttpRequest not doing the request everything works fine.

    Why is the Webview crashing if a XHR request is not possible and what can i doc to prevent this?

    Greetings

  3. Memory leaks in Internet Explorer 11

    I am using the Internet Explorer 11, I am developing the Web Application in the ASP.NET MVC using C# in Visual Studio 2015.

    I am trying to refresh the content of the web page using the XMLHttpRequest and it's worked find and content of the page is successfully changed, I am using the setInterval() for the constantly changing the content of the page.

    But however In Internet Explorer 11 memory is constantly increasing, It does not free automatically, But when run the same program in other browsers it works good, memory is free automatically, but in IE 11 it is not. After doing the R&D of the 6 days I
    comes to conclusion that there is fault in the IE11, IE11 can not able to handle the setInterval and XMLHttpRequest. It can not free the memory, I write the workaround for both but Still it can not works.

    How can I solve the problem of the memory free in IE11?
