Automate logging in to website using c#
Question
I want to login to a website every 5 hours to automate some tasks. I am having trouble login in because the website uses https.
I want to login to https://www.dealercentral.net . If I use fiddler meanwhile logging in this is the request and response that I captured where the username and password are being sent (note I modified the username and password for security reason otherwise you will be able to login to my account lol):
Request captured by fidler:

If I where to have __LASTFOCUS=&__VIEWSTATE=%2FwEPBSpWU0tleTo3ND.... etc and all the cookies I will be able to sign in. Once logged in I know what request I have to made in order to parse the data that I need. Its just I am having trouble logging in. I am also doing this to learn. I know there are a lot of web automators out there.
I know how to sign in with fiddlers help (If I copy the headers and posted data that was captured using fiddler sign in works!):
WebClient c = new WebClient();
c.Headers.Add("Cookie", "ASP.NET_SessionId=52lhv2bm45z5xx0kylecwzco; WSS_FullScreenMode=false");
// add other headers captured by fiddler
var html = c.UploadString("https://www.dealercentral.net", "__LASTFOCUS=&__VIEWSTATE=%2FwEPBSpWU0tleTo3NDM1NGQ1ZS1iYjBkLTQ2ODktYTU4Mi0xMDgzNTljY2ZjY2Zk7GQ77o%2B8NvANoTxtWC0wkDqyACylBde9E2t7U%2BOXkCY%3D&__EVENTTARGET=&__EVENTARGUMENT=&__EVENTVALIDATION=%2FwEdAATYiJ%2B%2Fud3KAWRxdbdx6iTIIRPZSl6UajYNUBbXmOsn5sIjdzfOst76JdbTNlFHv6h6%2Ff%2BTYHJ2sj56xvBVZVdouyYzuVuGagw4zrs8XpBj6eWYF7phR6ki3BEBwJxSZQ0%3D&signInControl%24UserName=USERNAME_I_MODIFIED_THIS_ON_PURPOSE&signInControl%24password=_PASSWORD_THAT_I_ENTERED_&signInControl%24login=Sign+In");

The response is ok and the login is successful.
Your login url is:
https://www.dealercentral.net/_layouts/15/dealercentral/login.aspx?ReturnUrl=%2f_layouts%2f15%2fAuthenticate.aspx%3fSource%3d%252F&Source=%2f
So, when login completes, the server response is:
Object moved to <a href="/_layouts/15/Authenticate.aspx?Source=%2F">here</a>.
which means the server is redirecting to that url because your login is ok.
