"$" dollar symbol, cookie name prefix

Question

I have this function to recover response files in CookieContainer (this.cookies)

private void getCookies(string url) { // request HttpWebRequest request = CreateWebRequestObject(url); request.CookieContainer = this.cookies; request.Headers.Add("Accept-Encoding", "gzip, deflate"); request.Headers.Add("Accept-Language", " es-MX,es;q=0.8,en-us;q=0.5,en;q=0.3"); request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"; request.Method = "GET"; request.UserAgent = "Mozilla/5.0 (Windows NT 5.1; rv:10.0.2) Gecko/20100101 Firefox/10.0.2"; // response using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { foreach (Cookie c in response.Cookies) { this.cookies.Add(new Cookie(c.Name, c.Value, c.Path, c.Domain)); } } } 

But when I debug the request in Fiddler, I get the following:

Why do cookies have "$"?

According to MSDN

public cookie (string name, string value, string path, domain string)

Name Type: System.String Name of the cookie. The following characters should not be used inside the name: equal sign, semicolon, comma, new line (\ n), return (\ r), tab (\ t) and space character. The dollar sign ("$") cannot be the first character.

How to remove this character?

Answer 1

You see that this is not a cookie name; This is the attribute associated with the cookie.

RFC 2109 relates to HTTP state management; Section 4.4 specifically deals with the dollar sign prefix. Hope this helps ...
