摘要： Techniques are provided for the caching of content prior to the content being requested. A request for desired content may be received from a client application at a caching server. The request may also indicate additional content related to the desired content that may be subsequently requested by the client application. The indicated additional content (and the desired content, if not already cached) is retrieved from an origin server. The desired content is transmitted to the client application at the user device, and the additional content is cached at the caching server. Subsequently, a second request may be received from the client application that includes a request for the additional content. The additional content, which is now cached at the caching server, is served to the client application by the caching server in response to the second request (rather than being retrieved from the origin server).

摘要： A data certification system and method for signing electronic data with a digital signature in which a central server comprises a signature server and an authentication server. The signature server securely stores the private cryptographic keys of a number of users. The user contacts the central server using a workstation through the secure tunnel which is set up for the purpose. The user supplies a password or other token based on information previously supplied to the user by the authentication server through a separate authentication channel. The authentication server provides the signature server with a derived version of the same information through a permanent secure tunnel between the servers, which is compared with the one supplied by the user. If they match, data received from the user is signed with the user's private key.

摘要： This invention generally relates methods, computer program code, data processing apparatus, and signals for certifying data, in particular by means of an electronic signature. Embodiments of the invention can be implemented on a user terminal without the need for dedicated hardware or software and may be termed “zero-footprint” data certification methods. A method of providing an electronic signature to-a-server; the method including receiving data for said server at a proxy system for said server; reading said received data to identify a signature request; obtaining a signature for a portion of said received data associated with said request responsive to said request, and providing said signature from said proxy system to said server. The use of a signature-enabled reverse proxy enables the use of a zero footprint user terminal, that is without the need to add additional functionality to the terminal for the purposes of signature creation in the context of a distributed application architecture.
