20090037393 | System and Method of Accessing a Document Efficiently Through Multi-Tier Web Caching - Upon receipt of a document request, a client assistant examines its cache for the document. If not successful, a server searches for the requested document in its cache. If the server copy is still not fresh or not found, the server seeks the document from its host. If the host cannot provide the copy, the server seeks it from a document repository. Certain documents are identified from the document repository as being fresh or stable. Information about each these identified documents is transmitted to the server which inserts entries into an index if the index does not already contain an entry for the document. If and when this particular document is requested, the document will not be present in the server, however the server will contain an entry directing the server to obtain the document from the document repository rather than the document's web host. | 02-05-2009 |

20120317187 | Prioritized Preloading of Documents to Client - The present invention is directed to a client-server network system implementing a multi-tier caching strategy for a user to access a document efficiently. When serving a document to client, the document is examined for embedded references to other documents. The embedded references are extracted and then assigned a priority. the referenced documents are preloaded to the client prior to receiving a request for them. The referenced documents are obtained locally from the server cache or obtained from their respective web hosts and transmitted according to the assigned priority. | 12-13-2012 |
20120317188 | Refreshing Cached Documents and Storing Differential Document Content - The present invention is directed to a method for updating a cache. A server identifies whether certain preconditions have been met for a document in a cache from freshness parameters associated with a document identifier for the document. Then when the preconditions have been met, a first document content is retrieved from a remote host. A first content fingerprint for the first document content is calculated. The first document content is stored in the cache. Then a content difference is calculated between the first document content and a second document content, both associated with the document identifier. The content difference is stored. Then the document identifier is associated with the content difference. | 12-13-2012 |
