Can the value of a Site Property be changed in Service Center during application runtime?

The value of a Site Property can indeed be changed in Service Center during application runtime, which allows for dynamic adjustments to application behavior without the need for redeployment. This ability serves as a powerful feature, enabling developers to modify configuration settings, connections, or application features on-the-fly based on different needs, such as adapting to user demands or debugging.

Service Center provides an interface where these properties can be accessed and modified by users with appropriate permissions. When a Site Property is altered, the changes can directly impact the live application, altering its behavior and functionalities to suit immediate requirements or strategic adjustments.

In this context, the other options do not accurately reflect the capability and usage of Site Properties. For instance, Site Properties are not fixed after deployment as they can be modified as needed, nor are they limited to only single sessions or exclusive to admin visibility. Therefore, the flexibility to change them at runtime is a crucial aspect of managing OutSystems applications effectively.
