The HTTP Available-Dictionary request header allows the browser to specify the best matching dictionary it has to allow the server to use Compression Dictionary Transport for a resource request.

Clients can send an Available-Dictionary header when they support dcb or dcz encodings. The header is a colon-surrounded base-64 encoded SHA-256 hash of the dictionary contents.

See the Compression Dictionary Transport guide for more information.
