Uploadify (Session and authentication) with ASP.NET MVC

To correct this I propose you a solution… Send the auth cookie value and session id cookie value with uploadify and recreate it before session is retrieved.

here is the code to implent in the view :

<script>
    var auth = "<% = Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value %>";
    var ASPSESSID = "<%= Session.SessionID %>";

    $("#uploadifyLogo").uploadify({
        ...
        formData: { ASPSESSID: ASPSESSID, AUTHID: auth }
    });

And then in Global.asax :

protected void Application_BeginRequest(object sender, EventArgs e)
    {
      /* we guess at this point session is not already retrieved by application so we recreate cookie with the session id... */
        try
        {
            string session_param_name = "ASPSESSID";
            string session_cookie_name = "ASP.NET_SessionId";

            if (HttpContext.Current.Request.Form[session_param_name] != null)
            {
                UpdateCookie(session_cookie_name, HttpContext.Current.Request.Form[session_param_name]);
            }
            else if (HttpContext.Current.Request.QueryString[session_param_name] != null)
            {
                UpdateCookie(session_cookie_name, HttpContext.Current.Request.QueryString[session_param_name]);
            }
        }
        catch
        {
        }

        try
        {
            string auth_param_name = "AUTHID";
            string auth_cookie_name = FormsAuthentication.FormsCookieName;

            if (HttpContext.Current.Request.Form[auth_param_name] != null)
            {
                UpdateCookie(auth_cookie_name, HttpContext.Current.Request.Form[auth_param_name]);
            }
            else if (HttpContext.Current.Request.QueryString[auth_param_name] != null)
            {
                UpdateCookie(auth_cookie_name, HttpContext.Current.Request.QueryString[auth_param_name]);
            }

        }
        catch
        {
        }
    }

    private void UpdateCookie(string cookie_name, string cookie_value)
    {
        HttpCookie cookie = HttpContext.Current.Request.Cookies.Get(cookie_name);
        if (null == cookie)
        {
            cookie = new HttpCookie(cookie_name);
        }
        cookie.Value = cookie_value;
        HttpContext.Current.Request.Cookies.Set(cookie);
    }

And voila, with that method it’s totally transparent.

hope it help some!! 😉

EDITED : use formData instead of scriptData
