If this header is set, its value MUST be a MIME type that describes the format of the body. Otherwise, the receiver SHOULD consider the body to be a binary blob.

receipt

abstract val receipt: String?

Any client frame other than CONNECT MAY specify a receipt header with an arbitrary value. This will cause the server to acknowledge the processing of the client frame with a RECEIPT frame.

Functions

asMap

abstract fun asMap(): Map<String, String>

Returns a Map view of these headers.

get

abstract operator fun get(headerName: String): String?
