Hello.

I have two subdomains:  
[a.example.com](http://a.example.com)  
[b.example.com](http://b.example.com)

How do I make sure that the cart is saved when I switch from one subdomain to another?

Litium version: 8.11.6

You can tell litium to save the cart.  
Since it is two different domains cookies will be handled in same manner as if they where two completely different domains.

I remember that setting - but I can’t seem to find it in L8.

I will try setting the domain using OnAppendCookie for the CookiePolicyOptions

HI you can try this in `services.Configure<CookiePolicyOptions>()` on the Startup.cs:

```auto
options.OnAppendCookie = x =>
{
    if (x.Context.Request.Host.Host.EndsWith(".example.com"))
    {
        x.CookieOptions.Domain = ".example.com";
    }
};
options.OnDeleteCookie = x =>
{
    if (x.Context.Request.Host.Host.EndsWith(".example.com"))
    {
        x.CookieOptions.Domain = ".example.com";
    }
};

```
