.Net Web API - GetCookie() returns empty collection

Question

I tried to read a language cookie (which i set on the client) in an ApiController in my backend Web API like this:

var cookieHeaderValue = Request.Headers.GetCookies("lang").FirstOrDefault();

and my request header looks like this:

also the line

Request.Headers.GetCookies();

returns an empty Collection... Can anybody tell my why and what i can do against it? Please help

Answer 1

The parsing of the CookieHeaderValue will fail because of the '?' in your authentication cookie name. Try to remove the questionmark.
