Abstract
This document specifies a mechanism for dictionary-based compression in the Hypertext Transfer Protocol (HTTP). By utilizing this technique, clients and servers can reduce the size of transmitted data, leading to improved performance and reduced bandwidth consumption. This document extends existing HTTP compression methods and provides guidelines for the delivery and use of compression dictionaries within the HTTP protocol.
For the definition of Status, see RFC 2026.
