CACHING ELECTRONIC DOCUMENT RESOURCES IN A CLIENT DEVICE HAVING AN ELECTRONIC RESOURCE DATABASE

An electronic document references one or more electronic document resources stored on a host device. The host device may indicate in the electronic document that an electronic document is cacheable by a client device. When an electronic document resource is identified as cacheable by the client device, the client device caches the electronic document resource in a database stored in a computer-readable medium of the client device. The client device may also generate an electronic document resource catalog that identifies those electronic document resources that are cached in the database. When the client device next requests the electronic document from the host device, the client device may transmit the electronic document resource catalog to the host device. Upon receiving the electronic document resource catalog, the host device may modify the electronic document so that the electronic document references the electronic document resources cached in the database of the client device.
