ASP.Net Session Cookie Lost on mozilla/netscape After return from cross domain

Hi All,

I am suffering from a problem as described followed,

I have made an forms authenticated application and this is tied up with an payment gateway provider for money transections.
process flow is

1. user book any thing on my site then go to checkout option
2. On checkout i m redirecting my user to PG site with post values and post method.
3. User successfully reached at PG site , there he login and Pay his billed amount. then PG site redirect user to my site same as post method with posted values.
4. Problem Starts here , that when user come back to my site application redirect user to login.(only in mozilla and Netscape Browser)

I have tryed following things.

1. use Cookie mode="URI" (but now IE creates same prob)
2. Set auth cookie and make expiration long.
3. IIS session extented for 1 hour.

and many approchechs...........

Please reply as soon as possible.

Thanks for reply & sorry for replying late,

I would have done that by many other process like save context in db before redirecting and after come back can re generate the session on the basis of
IP, cookie etc but in all that process i had to loss previous session, which are very essential for my app.

anyway but after some time of posting here, i had found the reason and solution of this 'Silly problem' .

The Problem is basically related to domain name means URL,
my app does not redirect the request like

(I) abc-com To (II) www--abc-com

When user loggin by the (I) the browser makes session cookie with domain without 'www' but payment gateway redirect to (II) means with 'www' so browser makes another session cookie as different domain.

Resolution

I modified my app from global.asax in method of Application_Request to redirect user from first request to www .(if not coming) with status code "301".
below is the code.

void Application_BeginRequest(object ob, EventArgs e)
{
if (HttpContext.Current.Request.Url.ToString().ToLowe r().Contains("--abc-com"))
{
HttpContext.Current.Response.Status ="301 Moved Permanently";
HttpContext.Current.Response.AddHeader("Location", Request.Url.ToString().ToLower().Replace("--abc-com","--www-abc-com"));
}
}
