2. Why does the customer need this? (List the business requirements here)

Customer said:

~~~
As a platform operator, administrators are aware not to provide an empty key. However, many end-users do not understand the required fields. one end user is able to break the haproxy for all users of the platform.

~~~

Customer's concern is to prevent breaking the router even if the supplied key value is missing.
