Membership cookie with subdomain v 10.4
# help-with-umbracor

09/26/2023, 10:11 AMHi all,
I have an umbraco website running on (e.g.) www.mydomain.com and a separate site running on sub.mydomain.com which logs in via an API. I've set this in my startup (above "services.AddUmbraco()" in case that's relevant) :
services.ConfigureApplicationCookie(options =>
{
options.ExpireTimeSpan = TimeSpan.FromDays(365);
options.Cookie.Domain = ".mydomain.com";
});
I can see the cookie lifespan being changed to 365 days but it's ignoring the cookie domain and the cookie value is still set to www.mydomain.com.
This means when I log in via sub.mydomain.com no cookie is being returned. It logs me in, but I have no way of persisting that login if the user closes their browser. Is there another way I can set the cookie domain? Is it possible to set it from the API endpoint rather than startup?
Thanks in advance!

csharp
services.ConfigureApplicationCookie(options =>
{
var protectionProvider = DataProtectionProvider.Create(new DirectoryInfo(@"c:\shared-auth-ticket-keys\"));
options.Cookie.Name = ".AuthCookie";
options.Cookie.Expiration = TimeSpan.FromDays(7);
options.LoginPath = "/Account/Login";
options.Cookie.Domain = ".example.com";
options.DataProtectionProvider = protectionProvider;
options.TicketDataFormat = new TicketDataFormat(protectionProvider.CreateProtector("Microsoft.AspNetCore.Authentication.Cookies.CookieAuthenticationMiddleware", "Cookies", "v2"));
});huwred

09/26/2023, 10:34 AMthank you @huwred, will give that a go. Would the API technically be a separate login path? I have a controller endpoint for www.mydomain.com which would be "/login", but the API endpoint is "api/account/login"?

09/26/2023, 4:10 PM@huwred will DirectoryInfo(@"c:\shared-auth-ticket-keys\" work on a azure webapp hosted approach rather than a server?

09/26/2023, 8:38 PMThanks @huwred , I think Allen's comment is for the back office cookie rather than members?
