- If P4 AS is configured for your P4 Server, logging out of P4 Code Review will not invalidate your Identity Provider (IdP) login status. If you try to log back in to P4 Code Review while your IdP status is still valid, you will not be prompted to complete the log in steps.

If require_login is also enabled, P4 Code Review will return you to the login and your IdP will automatically log you back in. In this case log out from your Identity Provider page before logging out from P4 Code Review.

- If a custom redirect has been configured by your P4 Code Review administrator, you are logged out of P4 Code Review and then redirected to the URL specified by the administrator.

The custom redirect can be set to any internal or external URL, for example:

- Company intranet, extranet, internet, FTP, or Web-mail page
- Industry news website
- Identity Provider page to invalidate your IdP log in status
