A global server load balancing (GSLB) switch serves as a proxy to an authoritative DNS communicates with numerous site switches which are coupled to host servers serving specific applications. The GSLB switch receives from site switches operational information regarding host servers within the site switches neighborhood. When a client program requests a resolution of a host name, the GSLB switch, acting as a proxy of an authoritative DNS, returns one or more ordered IP addresses for the host name. The IP addresses are ordered using metrics that include the information collected from the site switches. In one instance, the GSLB switch places the address that is deemed “best” at the top of the list.

A remote browsing process is directed to the generation and management of a remote persistent browsing context at a network computing provider. A client computing device requests a remote persistent browsing context instance at a network computing provider. The network computing provider provides processing results corresponding to processed representations of requested content to the client computing device. The persistent browsing context may be maintained at the network computing provider subsequent to the user ending his interaction with the browser application at the client device. A client computing device may subsequently request access to the persistent browsing context maintained at the network computing and storage device.

Systems and techniques to provide distributed document version control. In general, in one implementation, the technique includes: receiving a request to take an action with respect to a distributed electronic document, identifying, in response to the request, information associated with the distributed electronic document, the associated information indicating a second electronic document different from the distributed electronic document, and imparting information concerning the second electronic document to force the action to be taken with respect to the second electronic document. Receiving the request can occur at a server, and the request can be from a client to take the action with respect to the distributed electronic document, retained locally at the client. The associated information can be retained at the server, and imparting the second document information can involve relating the second document information (e.g., the second document or a link to it) from the server to the client.

Distributed document version control

An aspect of the present invention is a method for routing content information to a mobile user or client application. The method preferably comprises re-directing a user request to one or more gateway servers provided via an overlay network. In another aspect, the present invention is an apparatus that includes a proxy service that intercepts content information requests to the Internet and re-directs the content requests to an overlay. Another aspect of the present invention comprises a location-based Uniform Resource Locator that includes a protocol semantic portion and a location-based resolver address portion that identifies one or more resources on a network based on the geographical location of the resources.

A system and method of selecting a host for a client in a client-server network, such as the Internet. The method includes initiating a plurality of responses, such as domain name system (DNS) responses, in a race to the local server and/or client. The method determines the most suitable host or server based on its shortest latency with the client.

Method and system for selecting a host in a communications network

A method and a system are described for directing a client to the most optimal, most available Web site or to the most optimal content in a distributed content environment, using an Internet Site Selector, which is an Internet appliance that optimizes the performance of domains hosted on mirrored, geographically distributed Web sites. The system includes various components including the Internet Site Selectors which co-locate with each Web site. The method comprises a number of steps including sending client requests to a primary or main site, redirecting by an Internet Site Selector coupled to the primary or main site the modified client requests to all other participating Internet Site Selectors. Several modes and deployments of the Internet Site Selectors, including geographic site selection, multiple Internet Site Selectors at each Web site, Internet Site Selector grouping, Internet Site Selectors in content routing are described.

Method and apparatus for discovering client proximity

A system and method for determining a chronometrically optimal web site location for access by a client based on proximity measurements on established connections that are a result of requests for actual content. In one embodiment, the technique involves a race condition between local domains each transmitting TCP packets loaded with a HyperText Markup Language (HTML) Base tag identifying that local domain. The earliest received TCP packet is incorporated into the TCP stream. In another embodiment, the technique involves a race condition between local domains each transmitting files having links to streaming media translated to point to its own local domain. The earliest received file is incorporated into the TCP stream while the others are discarded as TCP resends. In yet another embodiment, HTTP redirect operations are performed once for each grouping of links only the earliest redirect packet to reach the client is incorporated into the existing TCP stream.

Method and apparatus for discovering client proximity network sites

A system of redirecting encrypted requests for content at a web site includes the steps of receiving, at a first web site, data enabling secure communication with a client, receiving, at the first web site, a request for content from the client, identifying an alternate web site to service the request from the client and forwarding a communication associated with the request to the alternate web site including forwarding the data enabling secure communication to the alternative web site. Such an arrangement allows a web site to communicate with a client using encrypted packets without having previously set up a tunneled connection, thereby aiding in disaster recovery and providing a facilitating client proximity detection when traffic is encrypted.
