.NET Framework Class Library

HttpCookie..::.Secure Property

Gets or sets a value indicating whether to transmit the cookie using Secure Sockets Layer (SSL)--that is, over HTTPS only.

Namespace: System.Web
Assembly: System.Web (in System.Web.dll)

Syntax

Visual Basic (Declaration)

Public Property Secure As Boolean

Visual Basic (Usage)

Dim instance As HttpCookie
Dim value As Boolean

value = instance.Secure

instance.Secure = value

public bool Secure { get; set; }

Visual C++

public:
property bool Secure {
    bool get ();
    void set (bool value);
}

JScript

public function get Secure () : boolean
public function set Secure (value : boolean)

Property Value

Type: System..::.Boolean
true to transmit the cookie over an SSL connection (HTTPS); otherwise, false. The default value is false.

Remarks

To set the transmission of cookies using SSL for an entire application, enable it in the application's configuration file, Web.config, which resides in the root directory of the application. For more information, see httpCookies Element (ASP.NET Settings Schema). Values set programmatically using the Secure property override values set in the Web.config file.

When dealing with sensitive information, it is strongly recommended that you use HTTPS protocol with SSL encryption. SSL protects against data being altered (data integrity), protects a user's identity (confidentiality), and assures that data originates from the expected client (authentication). For more information on the benefits of encryption, see Cryptography Overview. For more information about configuring SSL on an Internet Information Services (IIS) Web server, see Configuring SSL on a Web Server or a Web Site.

Examples

The following code example takes action if the cookie is set to transmit using SSL.

Visual Basic

If MyCookie.Secure Then
    '...
 End If

if (MyCookie.Secure)
 {
   //...
 }

JScript

if(myCookie.Secure){
    //...
 }
