Gets or sets a value indicating whether to transmit the cookie using Secure Sockets Layer (SSL)--that is, over HTTPS only.
Assembly: System.Web (in System.Web.dll)
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 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 Cryptographic Services. 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.
