RequireSSL Property

FormsAuthentication.RequireSSL Property

Gets a value indicating whether the forms-authentication cookie requires SSL in order to be returned to the server.

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

public static bool RequireSSL { get; }

Property Value

Type: System.Boolean
true if SSL is required to return the forms-authentication cookie to the server; otherwise, false. The default is false.

The RequireSSL property value is set in the configuration file for an ASP.NET application by using the requireSSL attribute of the forms configuration element. You can specify in the Web.config file for your ASP.NET application whether SSL (Secure Sockets Layer) is required to return the forms-authentication cookie to the server by setting the requireSSL attribute . For more information, see Secure.

It is recommended that if you configure requireSSL as false, you also configure slidingExpiration as false, to reduce the amount of time for which a ticket is valid.

The following code example sets the requireSSL attribute in the Web.config file.

<authentication mode="Forms">
  <forms loginUrl="member_login.aspx"
    cookieless="UseCookies"
    requireSSL="true"
    path="/MyApplication" />
</authentication>
