How to create persistent Cookie from HttpContext's Cookie.Append method?

Mahesh Kumar 65

var token = await _jwtTokenService.GenerateToken(user);
HttpContext.Response.Cookies.Append("accessToken", token, new CookieOptions
{
    HttpOnly = true,
    Expires = DateTime.UtcNow.AddHours(1),
    SameSite = SameSiteMode.None,
    Secure = false,
    IsEssential = true,
    
});

I am attaching the token in Cookie with the help of HttpContext

I can't find a way to make it persistent . Right now, on refreshing the page, the cookie is destroyed automatically. I want it to stay in the browser ever after closing the page until its expiry date. How do i do it?

Hi Mahesh, I have some ideas on your case. Firstly, could you please set a longer time for Expire time to rule out the eliminate interference from time differences, such as setting the value to be 1 day. Then could you please help checking whether you had some other global cookie policies such as the settings in Program.cs. By the way, could you please change to use SameSiteMode.Lax just for testing purpose? And finally, may I know does this issue occur in other browsers? I think it's a good idea to test in different browsers and not test in the private window.

builder.Services.Configure<CookiePolicyOptions>(options => { options.MinimumSameSitePolicy = SameSiteMode.Lax; });

I'm guessing you are trying to set a cookie in a Web API application. By default Web API is not setup to use cookies.

If I'm correct, then you should be setting the cookie in the client application not Web API.

Hi Mahesh, may I know whether there's any update in this question? I have another test today and I found if I use SameSite = SameSiteMode.None, Secure = true could also work well.
