I'm trying to login to a website via my application.
What I did:
First I figured out how the browser does the authorization process with Fiddler.
I examined how the POST request is built and I tried to reconstruct it.
The browser sends 4 cookies (Google Analytics) and I tried to set them:
CookieContainer gaCookies = new CookieContainer();
gaCookies.Add(new Cookie("__utma", "#########.###########.##########.##########.##########.#"));
gaCookies.Add(new Cookie("__utmb", "#########.#.##.##########"));
gaCookies.Add(new Cookie("__utmc", "#########"));
gaCookies.Add(new Cookie("__utmz", "#########.##########.#.#.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)"));
(just replaced the original cookie data with #)
Then I went through the code with the debugger and as soon as the first gaCookies.Add is executed, the application stops with an
System.ArgumentException: The parameter '{0}' cannot be an empty string. Parameter name: cookie.Domain
I would like to know why this happens. The constructor of Cookie doesn't require a domain and I don't know where I can get this value?
Would be very great if someone of you could help me with this.
I'm not a webdeveloper or an expert in web stuff so I don't know much about it.
Is there maybe a great source where I can learn about this if there is no "short and quick answer"?
