A Web cache (or HTTP cache) is an information technology for the temporary storage (caching) of Web documents, such as Web pages, images, and other types of Web multimedia, to reduce server lag. A Web cache system stores copies of documents passing through it; subsequent requests may be satisfied from the cache if certain conditions are met. A Web cache system can refer either to an appliance or to a computer program.
Method for high-performance delivery of web content
InactiveUS20050044270A1Improve performanceReduce deliveryDigital computer detailsData switching networksWeb serviceWeb cache
The present invention provides a method and apparatus for increasing the performance of world-wide-web traffic over the Internet. A distributed network of specialized nodes of two types is dispersed around the Internet. A web client's requests are directed to a node of the first type chosen to be close to the client, and the client communicates with this node using a standard protocol such as HTTP. This first node receives the request, and communicates the request to a node of the second type chosen to be close to the request's ultimate destination (e.g., a web server capable of generating a response to the request.) The first node communicates the request to the second node using a different, specialized, protocol that has been designed for improved performance and specifically to reduce traffic volume and to reduce latency. The second node receives communication from the first node using this specialized protocol, converts it back to a standard protocol such as HTTP, and forwards the request to the destination computer or server. Responses from the destination to the client take the corresponding reverse route, and also are carried over a specialized protocol between the two nodes. In addition, these nodes can employ other techniques such as web caches that avoid or improve some communication steps. Thus, specialized, proprietary, or complex protocols and techniques can be quickly deployed to enhance web performance without requiring significant changes to the clients or servers.

Method and apparatus for transparent distributed network-attached storage with web cache communication protocol/anycast and file handle redundancy
ActiveUS7254636B1Data processing applicationsDigital data processing detailsContent distributionNetwork connection
A distributed network-attached storage network provides content distribution using conventional file transfer protocols such as NFS and CIFS. A filer proxy accepts a client request and translates the client request to a file transfer protocol accepted at the file system having the file requested in the client request. The filer proxy generates a file handle for the file containing redundant filer proxy information to be used for failover to a backup filer proxy in the event of a network error or failure of an original filer proxy. The file handle also contains information for network security purposes such as detection of forged file handles.

System and method of accessing a document efficiently through multi-tier web caching
ActiveUS7437364B1Data processing applicationsSpecial data processing applicationsWeb cacheDocument preparation
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.

Gathering enriched web server activity data of cached web content
A method and system for gathering enriched web server activity data in a global communications network in which requested information files are cached at a plurality of network devices. With the prevalence of web caching on the Internet, the origin web servers do not serve the majority of requests for web site content. A single pixel clear Graphics Image Format (GIF) request is added to the HyperText Markup Language (HTML) source file for a web page. Appended to the GIF request is a Common Gateway Interface (CGI) string of data that contains enhanced web activity data information, including the number of images (“hits”) that have to be retrieved by a client browser to build the web page, and the referring identifier that resulted in access to the web page. The single pixel clear GIF request is not cacheable and results in the request being transmitted to the origin web server when the client browser interprets the HTML file. The enriched data is stored in log files at the origin web server to accumulate an accurate number of hits on the web page.

Memory admission control based on object size or request frequency
InactiveUS7051161B2Improved memory operationImprove operationDigital data information retrievalSpecial data processing applicationsObject basedParallel computing
Admission of new objects into a memory such as a web cache is selectively controlled. If an object is not in the cache, but has been requested a specified number of prior occasions (e.g., if the object has been requested at least once before), it is admitted into the cache regardless of size. If the object has not previously been requested the specified number of times, the object is admitted into the cache if the object satisfies a specified size criterion (e.g., if it is smaller than the average size of objects currently stored in the cache). To make room for new objects, other objects are evicted from the cache on, e.g., a Least Recently Used (LRU) basis. The invention could be implemented on existing web caches, on distributed web caches, in client-side web caching, and in contexts unrelated to web object caching.

ActiveUS8224964B1Raise priorityMultiple digital computer combinationsTransmissionWeb cacheClient-side
A client-server network system implements 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 documents referenced are obtained locally from the server cache or obtained from their respective web hosts and transmitted according to the assigned priority. If the client determines that it has the document, the transmission of is terminated. If the client or server determines that a newly requested document is one of the referenced documents being transmitted, the transmission is given a higher priority. In some instances, the server calculates a content difference between a current version of a referenced and a previous version and transmits this content.

Methods and apparatus for managing access to data through a network device
InactiveUS7624184B1Facilitates returning responseImprove performanceMultiple digital computer combinationsTransmissionData accessNetwork addressing
The invention is directed to techniques for managing access to data available from a data access device using a network switching protocol to manage content requests from clients. A data communications device receives a request for content from a client. The data communications device, such as a network switch, exchanges signals using the network switching protocol with one or more data access devices, such as a web cache. The data communications device can then select one data access device to provide the requested content to the client based, for example, on load balancing considerations. The data communications device sends a data transfer approval signal to the selected data access device. The selected data access device establishes a connection with the client using information, such as the client's network address, provided by the signals. The selected data access device then bypasses the data communications device and sends the requested content to the client. Using the network switching protocol, the data communications device can manage multiple, pipelined requests from the same client, while approving responses to the client from different data access devices, such as web caches and / or servers.

Methods and apparatus slow-starting a web cache system
InactiveUS7069324B1Minimize overloadingEasy to useMultiple digital computer combinationsMemory systemsTraffic capacitySlow-start
Methods and apparatus are described for intelligently assigning a portion of a cluster's traffic (e.g., buckets) to a cache system to minimize overloading of such cache system. In general terms, when a new cache system enters a cache cluster and / or starts up, the new cache system's full bucket allocation is not immediately assigned to the new cache system. Instead, only a portion of the full bucket allocation is initially assigned to the new cache system. In one embodiment, the new cache system's bucket assignment is gradually increased until the cache system is handling it's full bucket allocation or it becomes overloaded. The cache system's load is also checked periodically to determine whether it has become overloaded. When the cache system becomes overloaded, buckets are immediately shed from the cache system. In sum, the new cache system's load is adjusted until it is handling an optimum number of buckets.
