  System.Net.Cookie用户等级和积分=
    新System.Net.Cookie（CUserType，用户，/，www.DOMAIN_NAME.com）;
userType.Expires = DateTime.Now.AddYears（1）;
System.Net.Cookie dUserType =
    新System.Net.Cookie（dCUserType，用户，/，www.DOMAIN_NAME.com）;
dUserType.Expires = DateTime.Now.AddYears（1）;System.Net.CookieContainer的CookieContainer =新System.Net.CookieContainer（）;
cookieContainer.Add（用户类型）;
cookieContainer.Add（dUserType）;HttpWebRequest的WebRequest的=（HttpWebRequest的）WebRequest.Create（URL）;webRequest.Proxy =新WebProxy（127.0.0.1，8888）;
webRequest.Referer =？的http：//DOMAIN_NAME/search/index.aspx盖= 3;

解决方案

当您设置cookies，您还需要设置域，因为cookies是不同的 www.domain.com 和刚 domain.com 。

为了让他们一样，你需要设置域在您的cookie。
首先在的web.config

 ＆LT;身份验证模式=表格＆GT;
 ＆LT;形式域=yoururl.com... /＆GT;
＆LT; /认证＆GT;
 

和第二，当你手动设置你的cookies（用了WWW）：

  Response.Cookies [cookieName]。域=yoururl.com;
 

或你设置它（与出子 WWW ）：

  System.Net.Cookie dUserType =
    新System.Net.Cookie（dCUserType，用户，/，DOMAIN_NAME.com）;

This is how I am setting up the cookies data and passing along web request. When I check the response from the website using fiddler I see cookies have no data and expiry data is set to Jan 1, 1900. Any help would be much appreciated. Please let me know if something is not clear from following code or you need more info to answer my question. Thanks.

System.Net.Cookie userType = 
    new System.Net.Cookie("CUserType","subscriber", "/", "www.DOMAIN_NAME.com");
userType.Expires = DateTime.Now.AddYears(1);
System.Net.Cookie dUserType = 
    new System.Net.Cookie("dCUserType", "subscriber", "/", "www.DOMAIN_NAME.com");
dUserType.Expires = DateTime.Now.AddYears(1);

System.Net.CookieContainer cookieContainer = new System.Net.CookieContainer();
cookieContainer.Add(userType);    
cookieContainer.Add(dUserType);

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(URL);

webRequest.Proxy = new WebProxy("127.0.0.1", 8888);   
webRequest.Referer = "http://DOMAIN_NAME/search/index.aspx?lid=3";  
webRequest.ContentType = "application/x-www-form-urlencoded";   
webRequest.Date = DateTime.Now;    
webRequest.CookieContainer = cookieContainer;

string result;

using (var stream = webRequest.GetResponse().GetResponseStream())
using (var reader = new StreamReader(stream, Encoding.UTF8))    
{
    result = reader.ReadToEnd();    
}

解决方案

When you set cookies, you also need to set the domain because the cookies are different for www.domain.com and just domain.com.

To make them the same, you need to set the domain on your cookie. First on the web.config

<authentication mode="Forms">
 <forms domain="yoururl.com" ... />
</authentication> 

and second when you set manually your cookies (with out the www.):

Response.Cookies[cookieName].Domain = "yoururl.com";

or as you set it up (with out the subdomain www.):

System.Net.Cookie dUserType = 
    new System.Net.Cookie("dCUserType", "subscriber", "/", "DOMAIN_NAME.com");
