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
