Technologies for cross-device shared web resource cache

Abstract

Technologies for cross-device shared web resource caching include a client device (102a) and a shared cache device (102b). The client device (102a) scans for a shared cache device (102b) in local proximity to the client device (102a) and, in response to the scan, registers with the shared cache device (102b). After registering, the client device (102a) requests a cached web resource from the shared cache device (102b). The shared cache device (102b) determines whether a cached web resource that matches the request is installed in a shared cache (102b). The shared cache device (102b) may determine whether an origin of the request matches the origin of the cached web resource. If installed, the shared cache device (102b) sends a found response and the cached web resource to the client device (102a). If not installed, the shared cache device (102b) sends a not-found response and the client device (102a) may request the web resource from a remote web server. Other embodiments are described and claimed.
