I have a website where I created a custom cookie and I am trying to read the cookie value inside my Custom Rewrite Provider running in IIS
Question in short: How to decrypt the cookie inside custom URL rewrite provider?
Below is the code for creating custom cookie
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1,
model.Email,
DateTime.Now,
DateTime.Now.AddDays(7),
true,
"deepak",
FormsAuthentication.FormsCookiePath);
string encryptedTicket = FormsAuthentication.Encrypt(ticket);
HttpCookie fCookie = new HttpCookie("customCookie", encryptedTicket);
fCookie.Expires = DateTime.Now.AddDays(7);
fCookie.Path = "/";
Response.Cookies.Add(fCookie);
Below code is to read the cookie value inside my Custom Rewrite Provider running in IIS
public class ParseUserNameProvider : IRewriteProvider, IProviderDescriptor
{
public IEnumerable<SettingDescriptor> GetSettings()
{
throw new NotImplementedException();
}
public void Initialize(IDictionary<string, string> settings, IRewriteContext rewriteContext)
{}
public string Rewrite(string value)
{
string[] val = value.Split('=');
string name = "";
if (val != null)
{
FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(val[1]);
if(authTicket!=null)
{
name = authTicket.Name;
}
}
return name;
}
}
I am getting a error as shown below
