`class Vary`

Represents the vary header, which specifies the request headers a server considers when determining the response.

The vary header is used in HTTP responses to indicate which request headers affect the selected response. It allows caches to differentiate stored responses based on specific request headers.

Definitions

`def initialize(value)`

Initializes a Vary header with the given value. The value is split into distinct entries and converted to lowercase for normalization.

	super(value.downcase)
end

`def <<(value)`

Adds one or more comma-separated values to the vary header. The values are converted to lowercase for normalization.

Signature

parameter　value　String: the value or values to add, separated by commas.

Implementation

	super(value.downcase)
end
