Abstract: One or more techniques and/or systems are disclosed for providing a client application with access to a file based upon a local offline version of the file and/or web online version of the file. That is, a file may be shared/synchronized from a remote source, such as a web storage service. A web online version of the file may be maintained by the web storage service, while local offline versions of the file may be stored at client devices. A sync module comprising knowledge of the local and/or web versions of the file may provide a client application with access to the file based upon the local and/or web version of the file. The sync module may also delegate synchronization authorization to the client application given that the client application may comprise sophisticated file handling functionality.

Abstract: One or more techniques and/or systems are provided for managing compression dictionaries. In particular, messages between a sender and a recipient may be compressed using a combination of static compression dictionaries and/or dynamic dictionaries. The static compression dictionaries may be updated with new dictionary entries based upon a recipient decompressing a compressed message received from a sender, a dynamic dictionary associated with the compressed message and/or a prepared response. In this way, the static dictionary may evolve over time to provide a flexible and customized approach for managing compression dictionaries. Dictionary versioning may be provided, such that a sender dictionary and a recipient dictionary may be updated to maintain synchronization.
