選択肢
- It creates a row for the signed in user in the access control table of the application so that a role can be granted to that user from the administration page.
- It decides which pages and which components the identified user is allowed to see and it stops the request with a message when that user fails the check that has been defined for the page.
- It establishes the identity of each user and the engine then keeps that identity in a built in substitution string that the developer can read from a query or from code as the session moves on.
- It adds a checksum to the addresses that the application generates so that a user cannot change the value of an item by editing the address of the page in the browser.
