摘要:
A method and system for transport data compression between a server and a client based on patches to the dictionaries used for encoding the data. The method includes requesting the server for data, returning the data and a dictionary patch to the client where data having been compressed based on a previously used dictionary and the dictionary patch, and decompressing the returned data using the dictionary and the dictionary patch. The dictionary patch includes updates to the previously used dictionary. Each dictionary has a dictionary identifier that the server and client use to identify the dictionary in their requests and responses. The identifier might be a unique identification or a network session number. Upon receiving a response, the client updates the previously used dictionary with information in the patch and decompresses the returned data using the updated dictionary.
