Dear Umbraco folk,

I am configuriing Membership for my new site Umbraco 7 MVC / UCommerce site and

After Members Login using my Login web page, they show as Online for the immediate next page only, but then fall offline for subsequent pages :-(

To summarize my code showing only relevant bits, this is how my Login page Logs a Member in:

    // Get the Umbraco MemberService
    var umbMemberService = AppHelpers.UmbServices().MemberService;
    // Get the Umbraco Member
    var umbracoMember = umbMemberService.GetByEmail(model.EmailAddress);
    // Create and instance of the MembershipHelper
    var membershipHelper = new MembershipHelper(UmbracoContext.Current);
    string thisUserName = umbracoMember.Username;
    if (membershipHelper.Login(thisUserName, model.Password))
    {
        // Do several actions for successful logon here including
        FormsAuthentication.SetAuthCookie(model.EmailAddress, true);
        // Note also that debugger shows FormsAuthentication.Timeout = {00:30:00}  or 30 minutes
    }

The Login page returns a redirect along with the following cookies in the Responce header (using IE Debug tools):

    yourAuthCookie=02C642782F0F8433291759C78F3B879FBF061C359EE74ACC4B214C0F7E1FDBE26FCA0E37CF61F3581BF8C2A7EE04304F2CACD4B8F44C4233EF845DDB6EB8A524BFF06D3C10CF5249F71C5844B6DF4310F4DF28410678B500A29FAFDF08B3439523BA8F08A3EF25C8C4F9FC9990F31A42;

    yourAuthCookie=4C1A7CA68BF4920036A90A682AD302395EA57B5FDC2682D143F86B8B7E23A669366A0EFA5D382E19EA59A895B2184323DF680E062734ED62ECF96B5B27E3B63E310F50146BC455C574B50B48611CA05ACBCD68DCC282559F6C7FDF89BD6AEA82DCCE94DF03DA92993D20ADE1F90103BC5537FC985279577D957C01775003924C;

I am not sure why there are TWO "yourAuthCookie"s ?? Anyway those time outs are 30 minutes in the future so that seems fine.

When the browser requests the redirect page, I see that the Request Header includes the following

   Cookie: basketid=4453f3e8-0240-4e89-b1b2-af4ed62a362d; pricegroup=7; UMB_UPDCHK=1; 
__RequestVerificationToken=EekALQkgIjZ6kgV08e7i27CMGDfPR3GtPZGgNZ8shzc5VwFnbS3rKJgBSpFPMfjRgCi6MRgYVpXS1wvRHZd3fImKuJKyHbSg-Kf-isYfW4M1; 
yourAuthCookie=4C1A7CA68BF4920036A90A682AD302395EA57B5FDC2682D143F86B8B7E23A669366A0EFA5D382E19EA59A895B2184323DF680E062734ED62ECF96B5B27E3B63E310F50146BC455C574B50B48611CA05ACBCD68DCC282559F6C7FDF89BD6AEA82DCCE94DF03DA92993D20ADE1F90103BC5537FC985279577D957C01775003924C

But I also see that the Responce Header with that page includes the following

Set-Cookie: yourAuthCookie=; expires=Tue, 12-Oct-1999 07:00:00 GMT; path=/; HttpOnly

WHICH IS IN THE PAST !!!! which probably explains why I am then logged out when I try and visit any subsequant pages.

Any clues as to what may be causing this and/or how to fix would be greatly appreciated.

Thanks very much
