043 – Define an explicit content type

Summary

All system files generated dynamically must have an explicitly defined content type.

Description

This configuration ensures that the appropriate content type is included in the HTTP response headers when the file is served. Programming languages may include code to set the content type based on the nature of the dynamically generated content. Additionally, web frameworks and libraries provide mechanisms for specifying content types in a clear way.
