I am trying to configure sessions for an asp.net core 2.0 website, but the session cookie is never set.
I call ..
app.UseSession();
...in Startup.Configure and ...
services.AddDistributedMemoryCache();
services.AddSession(options =>
{
options.IdleTimeout = TimeSpan.FromMinutes(10);
options.Cookie.HttpOnly = false;
options.Cookie.Name = "WS_AUTH_ID";
});
... in the ConfigureServices method.
In the Controller I can acess ...
HttpContext.Session.Id;
... but the id is always different for every request.
Am I missing something?
Update: I should metion that I can set cookies "manually" and the browser will "receive" them.
HttpContext.Response.Cookies.Append("Test_cookie", "yo");

Session cookies are essential for a website's functionalities or for it to deliver a service that it intends to. They are also exempt from consent requirements under privacy regulations like the GDPR.
Sessions are cookies dependent, whereas Cookies are not dependent on Session. The session ends when the user closes the browser or logout from the application, whereas Cookies expire at the set time. A session can store as much data as a user want, whereas Cookies have a limited size of 4KB.
ASP.NET Core maintains session state by providing a cookie to the client that contains a session ID. The cookie session ID: Is sent to the app with each request. Is used by the app to fetch the session data.
By default, SessionID values are stored in a cookie. However, you can also configure the application to store the SessionID value in the URL for a "cookieless" session.
If you have the cookie policy turned ON the session cookiewon't be created until the user accepts the use of Cookies, this is to comply with the EU's GDPR.
You can remove the line
app.UseCookiePolicy();
from you Startup and then it will work, otherwise your users will need to agree to the use of cookies before you can use the cookie for session control.
