hi Everyone,
I am using ASP.Net 2.0. When user logins, I check the credential and
then made the cookie. My hoster's server is in Arizona region and I am
in Pakistan. I set cookie's expiration time as 4 hours. It works
perfectly fine on my PC and many other PCs which have correct time.
But, if I set date to some old date, user is simply unable to login.
This makes sense as probably cookie timing is not matching. Dilemma is
that many users at home do not have correct time :( and probably thats
why, everyday we get 4-5 mails at support maintaining that they are
unable to login. Can you please tell me what I can do to resolve this
issue. This is the code I am using to create the ticket,

FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,
this.loginUser1.UserName, DateTime.Now, DateTime.Now.AddHours(4),
this.loginUser1.RememberMeSet, userData);

string cookieStr = FormsAuthentication.Encrypt(ticket);
HttpCookie cookie = new
HttpCookie(FormsAuthentication.FormsCookieName, cookieStr);
if (this.loginUser1.RememberMeSet)
{
cookie.Expires = ticket.Expiration;
}

cookie.Path = FormsAuthentication.FormsCookiePath;
Response.Cookies.Add(cookie);

And this is what I am doing in Global.asax's
Application_AuthenticateRequest function,

if (!(HttpContext.Current.User == null))
{
if (HttpContext.Current.User.Identity.AuthenticationType ==
"Forms")
{
System.Web.Security.FormsIdentity id;
id =
(System.Web.Security.FormsIdentity)HttpContext.Current.User.Identity;
string[] userData = id.Ticket.UserData.Split(new
string[] { "," },

StringSplitOptions.RemoveEmptyEntries);

HttpContext.Current.User = new
System.Security.Principal.GenericPrincipal(id, userData);
}
}

Bye,
Omer
