In which format does HttpRequestHeader.Cookies need to be specified? F.e, if I want to add cookie named CITY with value NY how should I do that with WebClient.Headers.Add() method?
To send cookies to the server, you need to add the "Cookie: name=value" header to your request. To send multiple Cookies in one cookie header, you can separate them with semicolons. In this Send Cookies example, we are sending HTTP cookies to the ReqBin echo URL.
A cookie is an HTTP request header i.e. used in the requests sent by the user to the server. It contains the cookies previously sent by the server using set-cookies. It is an optional header.
An HTTP cookie (web cookie, browser cookie) is a small piece of data that a server sends to a user's web browser. The browser may store the cookie and send it back to the same server with later requests.
The Set-Cookie HTTP response header is used to send a cookie from the server to the user agent, so that the user agent can send it back to the server later. To send multiple cookies, multiple Set-Cookie headers should be sent in the same response.
Try this sample
WebClient wb = new WebClient();
wb.Headers.Add(HttpRequestHeader.Cookie, "CITY=NY");
For many cookies:
wb.Headers.Add(HttpRequestHeader.Cookie, "cookiename1=cookievalue1; cookiename2=cookievalue2");
To add a cookie it's best and easiest to use Response.Cookies.Add();
HttpCookie myCookie = new HttpCookie("lastVisit");
myCookie.Value = DateTime.Now.ToString();
myCookie.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(myCookie);
Headers.Add:
myWebHeaderCollection.Add("CITY","NY");
Here is how your Cookie header should look like at the end rfc 6265:
Cookie: CITY=NY;
