Enable HTTP Only Cookie Flag

Use the glide.cookies.http_only property to enable the HTTPOnly attribute for sensitive cookies.

If the glide.cookies.http_only system property is not set to the recommended value of true, then the instance does not require the HTTPOnly attribute for sensitive cookies.

Ensure that the property glide.cookies.http_only is set to true.

Warning: This is a safe harbor property, meaning the value can't be altered once it's changed. It is non-revertible.
