Abstract

Techniques for storing objects (e.g., images) in and retrieving objects from a storage device (e.g., image store) in a rapid and efficient manner are disclosed. More particularly, the techniques include: storage of an object in and retrieval of an object from the storage device with reference to an object locator together with state and permission information, use of a directory structure of a file system to efficiently provide database structure for storage of the objects, storage and retrieval of object states as attributes of associated files in the file system, storage and retrieval of multiple versions of objects, and multi-threaded management of the storage device.

Claims20

Dependent claims

A proxy system for accelerated delivery of objects to a requester, the proxy system comprising:

an object storage device for storing objects, the object storage device using a file system that supports directories to store the objects in files at directory locations within the object storage device, for each of the objects the directory location where the object is to be stored is identified by an object locator associated with the network together with state and authorization information, wherein the combination of the object locater together with state and authorization information identify a unique slot in said object storage device;
and
a proxy server coupled between the requestors computer and a network of computers, wherein the proxy server intercepts a request for an object from the requestor's computer to the network of computers, and then satisfies the request by delivering the object requested from the object storage device to the requestor's computer, the object requested from the object storage device is retrieved from the object storage device using a combination of an object locator obtained from the request together with state and authorization information associated with the request.

Dependencies are inferred from the claim text.
