Attributes and Elements

The following sections describe attributes, child elements, and parent elements for this section.

Attributes

Attribute	Description
cacheRolesInCookie	Optional Boolean attribute. Specifies that when validating that a user is in a particular role, the cookie is checked before using the role provider to check the list of roles at the data source. If true, a list of role names in a cookie is cached for the current user; otherwise, false. The default is false.
cookieName	Optional String attribute. Specifies the name of the cookie in which role names are stored. The default is ".ASPXROLES".
cookiePath	Optional String attribute. The path for the role names cookie. The default is "/".
cookieProtection	Optional CookieProtection attribute. Specifies one of the CookieProtection enumeration values. The default is the All value.
cookieRequireSSL	Optional Boolean attribute. Specifies whether the role names cookie requires SSL to be setn to the server. If set to true, role names cookies require SSL to be sent to the server. The default is false.
cookieSlidingExpiration	Optional Boolean attribute. Specifies whether the expiration date and time of the role names cookie will be reset periodically. If set to true, the cookie expiration will at first be set to the current date and time plus the CookieTimeout value, in minutes. While the user continues to actively use the ASP.NET application, the expiration date and time of the cookie is automatically updated, if there is less than half of the CookieTimeout value remaining. For more information, see Expires. The default is true.
cookieTimeout	Optional Int32 attribute. The number of minutes before the role names cookie expires. The default is "30" (minutes).
createPersistentCookie	Optional Boolean attribute. Specifies whether the role names cookie is a session cookie; that is, the cookie is lost when the browser is closed.

      cookiePath="/"
      cookieRequireSSL="false"
      cookieSlidingExpiration="true"
      cookieProtection="All" >
      <providers>
        <add
