A multiple network protocol encoder / decoder comprising a network protocol layer, data handler, O.S. State machine, and memory manager state machines implemented at a hardware gate level. Network packets are received from a physical transport level mechanism by the network protocol layer state machine which decodes network protocols such as TCP, IP, User Datagram Protocol (UDP), PPP, and Raw Socket concurrently as each byte is received. Each protocol handler parses and strips header information immediately from the packet, requiring no intermediate memory. The resulting data are passed to the data handler which consists of data state machines that decode data formats such as email, graphics, Hypertext Transfer Protocol (HTTP), Java, and Hypertext Markup Language (HTML). Each data state machine reacts accordingly to the pertinent data, and any data that are required by more than one data state machine is provided to each state machine concurrently, and any data required more than once by a specific data state machine, are placed in a specific memory location with a pointer designating such data (thereby ensuring minimal memory usage). Resulting display data are immediately passed to a display controller. Any outgoing network packets are created by the data state machines and passed through the network protocol state machine which adds header information and forwards the resulting network packet via a transport level mechanism.

In various embodiments, a gateway application generates an outgoing Hypertext Transmission Protocol (HTTP) request based on an incoming HTTP request. In operation, the gateway application receives the incoming HTTP request and identifies an upstream service based on at least one of an HTTP method and a header included in the incoming HTTP request. Subsequently, the gateway application generates an outgoing HTTP request based on the upstream service and the incoming HTTP request. Finally, the gateway application issues the outgoing HTTP request. The outgoing HTTP request causes the upstream service to perform an action requested in the incoming HTTP request. Advantageously, the gateway application enables underlying upstream services to perform actions specified via incoming HTTP requests without directly exposing the upstream services to users.

A method of modifying network identifiers at data servers is disclosed. A virtual private network (VPN) gateway server generates a Hypertext Transfer Protocol (HTTP) request. The HTTP request not only requests data from a data server that is within a VPN, but also instructs the data server to modify (“mangle”) URLs that are contained within the requested data so that the URLs refer to the VPN gateway server. The VPN gateway server sends the HTTP request toward the data server. As a result, the data server modifies the URLs so that the VPN gateway server does not need to. When such a modified URLs is selected in a web browser, the web browser generates an HTTP request that is directed to the VPN gateway server's URL, which, unlike the unmodified URLs, can be resolved by domain name servers that are outside of the VPN.

Techniques are disclosed for addressing the name space mismatch between content caching systems (which use Uniform Resource Locators, or “URLs”) and content servers (which use file and path names). A file name-to-URL mapping is created for use by content caching systems, and data in protocol response messages (and optionally in protocol request messages) is augmented to transmit information for use in creating this mapping, enabling a content caching system to automatically and dynamically populate its file name-to-URL mapping. By having the file name available, the caching system can now respond to content management messages which identify the cached content by only the content's associated file name. Techniques for encoding the message extensions include: use of new directives on existing cache-control headers in Hypertext Transfer Protocol (“HTTP”) messages; addition of new headers in HTTP messages; and use of meta-data in markup languages such as Hypertext Markup Language (“HTML”) or Extensible Markup Language (“XML”) format.

The present invention is based on a concept to provide session and profile management for network communication, especially over hypertext transfer protocol (HTTP), employing available communication methods. Session and profile management is available and standardized for mobile communication by the means of the wireless session protocol (WSP) employable for wireless application protocol (WAP) communication. This wireless session protocol (WSP) is limited to mobile communication. The analog communication standard hypertext transfer protocol (HTTP) available and standardized for wireline communication does not offer a session and profile management. The present invention offers a method to establish an analog session and profile management by the means of cookies or modified uniform resource locators (URL) even over the hypertext transfer protocol (HTTP) without requiring substantial changes to the hypertext transfer protocol (HTTP) standard.

An internet server is controlled wherein the server receives a hypertext transfer protocol file request from a web browser over the internet and any identification signal included with the hypertext transfer protocol file request. The identification signal is compared with one or more predetermined identification signals and depending upon the result of the comparison a file may be transmitted from the server to the web browser.

A solution is provided that allows end users to search documents in multiple remote content repositories in an enterprise environment, while maintaining security of those documents. Additionally, end users are able to search for a document without knowing which server or directory it is stored under. This is accomplished by installing a search agent on the end user's machine. The search engine collects the metadata of authorized documents located in different repositories via a web protocol (such as Hypertext Transfer Protocol, or HTTP) and stores them in the user's local memory as “searchable links”. This solves the enterprise content search problem through the creation of searchable links of remote content objects in an end user's local machine while allowing emerging desktop-search technology to index them.

Techniques are disclosed for improving the serving of large objects (equivalently, large files) in distributed computing networks which include network-attached storage ("NAS"). Existing features of Hypertext Transfer Protocol ("HTTP") and of Web server implementations are leveraged to achieve performance improvements in a novel way, and thereby greatly facilitate introduction of the present invention into existing networking environments. In particular, objects meeting certain criteria may be served using "redirect files" in which a redirect status code is used to cause content retrieval requests to be automatically redirected from the requesting client device to the NAS, such that the requested content is served from the NAS rather than through a Web server from a Web server farm.

A system provides for secure communication between an electrical utility company and an electricity customer, such that the customer is able to shed one or more loads in response to a load shed command from the utility company. A system server of the customer periodically connects to a utility server of the utility company using a standard computer protocol, such as Hypertext Transfer Protocol (HTTP). The system server sends a request message via the Internet to the utility server. The request message provides data on the total possible load, the present power consumption, and the present load shed state of the electricity customer. The utility server receives the request message and responds to the request message by transmitting to the system server a response message, which includes a load shed command.
