Forms authentication cannot be authenticated in a distributed deployment?

The use of forms authentication for distributed deployment of applications is not successful, referring to some methods on the web.

Application deployment of two intranet servers: 192.168.1.19,192.168.1.87, using nginx load distribution, the configuration is identical; each can be logged in and run.

Processing after successful login at the following time

FormsAuthenticationTicket ticket =NewFormsAuthenticationTicket (1, Userinfo.nickname, (DateTime) Issuedatetime, (datetime) experation, ispersistent, UserData,            Formsauthentication.formscookiepath); HttpCookie Cookies=NewHttpCookie (Formsauthentication.formscookiename, Formsauthentication.encrypt (ticket)); Cookies.

AppendCookie (cookie); //Remove the permission cache data to retrieve the cached data againRemoverediscache (UserInfo); }

The following is the code for validation

            //test whether the HttpContext.Current.User.Identity.IsAuthenticated is valid in a distributed deploymentResponse.Write (string. Format ("test whether the HttpContext.Current.User.Identity.IsAuthenticated is valid in a distributed deployment isauthenticated:{0}", HttpContext.Current.User.Identity.IsAuthenticated)); Response.Write ("<br/>cookie output Start ============================="); foreach(stringCookieNameinchrequest.cookies) {varMyCookie =Request.cookies[cookiename]; if(MyCookie! =NULL) {Response.Write ("<br/>"+ CookieName +"contained in"+ MyCookie. Values.count +"a key"); if(MyCookie. Values.count >0)                    {                        foreach(stringSinchMyCookie. Values) {Response.Write ("<br/> ""+ S +""="+ Mycookie[s]. ToString () +";"); } }}} Response.Write ("<br/>cookie output Complete ============================="); Response.Write ("<br/>formscookiename="+formsauthentication.formscookiename); HttpCookie Authcookie=Httpcontext.current.request.cookies[formsauthentication.formscookiename]; if(Authcookie! =NULL) {FormsAuthenticationTicket AuthTicket=Formsauthentication.decrypt (Authcookie.value); if(AuthTicket! =NULL)                {                    stringUserData =Authticket.userdata; JavaScriptSerializer JavaScriptSerializer=NewJavaScriptSerializer (); varUserInfo = javascriptserializer.deserialize<baseuserinfo>(UserData); Response.Write ("<br/>nickname="+userinfo.nickname); }                Else{Response.Write ("<br/>authticket = null"); }            }            Else{Response.Write ("<br/>authcookie = null"); } Response.Write ("<br/>clientipaddress ="+userinredis.getcurrentipaddress (httpcontext.current)); Response.Write ("<br/>serveripaddress ="+ Request.ServerVariables.Get ("local_addr"));

After the deployment, log in to the system and access the test page

You can see that the current Access app is assigned to the 192.168.1.19.

Now stop the 192.168.1.19 application and visit the test page

As can be seen from the above, access is assigned to the 192.168.1.87, while the. gdzdauthenforms cookie used for authentication has not passed, and other cookies have been passed over.

What is the reason for this? The same domain name should say that cookies will be uploaded to the background.

Reference: Http://www.cnblogs.com/fish-li/archive/2012/04/15/2450571.html and other articles are not implemented, the server configuration is the same, supposedly, the same domain name, You should bring the cookie with you when you visit.
