class Split

Represents headers that can contain multiple distinct values separated by commas.

This isn't a specific header class is a utility for handling headers with comma-separated values, such as accept, cache-control, and other similar headers. The values are split and stored as an array internally, and serialized back to a comma-separated string when needed.
