| Description |
|---|
| The secure flag is an option that can be set by the application server when sending a new cookie to the user within an HTTP Response. The purpose of the secure flag is to prevent cookies from being observed by unauthorized parties due to the transmission of the cookie in clear text. By setting the secure flag, the browser will prevent the transmission of a cookie over an unencrypted channel. Lookup Service is configured to only be accessible over a Transport Layer Security (TLS) tunnel, but this cookie flag is still a recommended best practice. |
