Represents the settings that are related to Web page security validation.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
The security validation is specific to a user, site, and time period and expires after a configurable amount of time. When the user requests a page, the server returns the page with security validation inserted. When the user then submits the form, the server verifies the security validation and if it has changed, program execution is halted and a security exception is raised.
