Share session over subdomain work with IE but not with Firefox

Forean · Sep 26, 2012

I have an issue with sharing session over subdomains.I have an application wich can be access by

I set up my web.config file like this :\[code\]<httpCookies domain=".myapplication.com"/><authentication mode="Forms"><forms loginUrl="index.aspx" cookieless="UseCookies" timeout="60000" enableCrossAppRedirects="true" domain=".myapplication.com"/></authentication>\[/code\]"enableCrossAppRedirects" can be configured to true or false, nothing change.In IE, when I switch from on subdomain to another, I always use the same session. But with Firefox, each time, I change subdomain, a new session is created for each.I read lot of article on google but nothing work. I don't understand why Firefox is differentThis is a simple aspx code page to test by yourself\[code\]<%@ Import NameSpace="System" %><%@ Import NameSpace="System.Linq" %><%@ Import NameSpace="System.Data" %><%@ Import NameSpace="System.Configuration" %><%@ Import NameSpace="System.Collections" %><%@ Import NameSpace="System.Collections.Generic" %><%@ Import NameSpace="System.Web" %><%@ Import NameSpace="System.Web.Security" %><%@ Import NameSpace="System.Web.UI" %><%@ Import NameSpace="System.Web.UI.WebControls" %><%@ Import NameSpace="System.Web.UI.WebControls.WebParts" %><%@ Import NameSpace="System.Web.UI.HtmlControls" %><%@ Import NameSpace="System.Reflection" %><%@ Import NameSpace="System.Web.SessionState" %><script language="c#" runat="server">public void Page_Load(object sender, EventArgs e){Log("<b>Refresh twice to see result after switch to another subdomain</b>");if (Session["CREATION"] == null){string navigateur = HttpContext.Current.Request.ServerVariables["HTTP_USER_AGENT"].ToString ();if (navigateur.ToUpper().Contains("FIREFOX")){navigateur = "Firefox";}else if (navigateur.ToUpper().Contains("MSIE")){navigateur = "Internet Explorer";}Session["CREATION"] = "Session create at " + DateTime.Now.ToString("hh:mm:ss") + " by " + navigateur; }Session["HOST"] = Request.Headers["HOST"];Session["SESSIONID"] = Session.SessionID;CheckSession();}private void Log(string text){Label1.Text += text + "<br/>";}public void CheckSession(){object obj = typeof(HttpRuntime).GetProperty("CacheInternal", BindingFlags.NonPublic | BindingFlags.Static).GetValue(null, null); object[] obj2 = (object[])obj.GetType().GetField("_caches", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(obj);for (int i = 0; i < obj2.Length; i++){Hashtable c2 = (Hashtable)obj2.GetType().GetField("_entries", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(obj2);foreach (DictionaryEntry entry in c2){object o1 = entry.Value.GetType().GetProperty("Value", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(entry.Value, null);if (o1.GetType().ToString() == "System.Web.SessionState.InProcSessionState"){Log("<hr/>");SessionStateItemCollection sess = (SessionStateItemCollection)o1.GetType().GetField("_sessionItems", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(o1); if (sess != null){foreach (string key in sess.Keys){Label1.Text += key + " = " + sess[key] + "<br>";}}}}}}</script><html><body><form id="form1" runat="server"><asp:Label id="Label1" runat="server"/></form></body></html>\[/code\]Hope somebody could help me.Regards
