CookieContainer bug?
- by Salar
I'm confused how CookieContainer handles domain, so I create this test.
This test shows cookieContainer doesn't return any cookie for "site.com" but according to RFC it should return at least 2 cookies.
Isn't it a bug?
How make it to work?
Here is a discussion about this bug:
