Zusammenfassung:	This disclosure is directed to dictionary-based compression, which may be employed to achieve stateful header compression without maintaining a complete deflate state. The compressor may maintain a history of data streams compressed by the compressor, compressed according to a compression dictionary. Responsive to the compression of the one or more data streams, the compressor may delete the first compression dictionary from the memory. Subsequent to the deletion, the compressor may compress an additional data stream using the maintained history. The compressor may generate a second compression dictionary from at least one of: the maintained history and a portion of the additional data stream. The compressor may allocate memory for a compression state of the additional data stream and may load the maintained history into the compression state.
