Abstract: Embodiments disclosed herein provide a high performance content delivery system in which versions of content are cached for servicing web site requests containing the same uniform resource locator (URL). When a page is cached, certain metadata is also stored along with the page. That metadata includes a description of what extra attributes, if any, must be consulted to determine what version of content to serve in response to a request. When a request is fielded, a cache reader consults this metadata at a primary cache address, then extracts the values of attributes, if any are specified, and uses them in conjunction with the URL to search for an appropriate response at a secondary cache address. These attributes may include HTTP request headers, cookies, query string, and session variables. If no entry exists at the secondary address, the request is forwarded to a page generator at the back-end.

Abstract: A system and a method for accelerating delivery of a webpage by using a preloader file during a delay in fetching the web file are disclosed. When an end user makes a request through a client computer for a webpage, a Content Delivery Network (CDN) server sends the client a preloader file. The preloader file contains requests for resources that are likely to be part of the web file. The client downloads the resources, and the resources are saved in a browser cache. The preloader file also directs the client to request the webpage again. While the client is downloading the resources, the CDN server requests the web file from an origin server. The origin server composes the webpage and delivers the webpage to the CDN server. When the client makes a second request for the web file, the CDN server delivers the web file to the client. When the client renders the web file to display the webpage, the client can retrieve the resources from the browser cache.

Abstract: The described embodiments electronically deliver content (e.g., digitally-encoded files) to an electronic device using groups of accounts. In the described embodiments, a content provider obtains a public address of the electronic device and at least one account identifier for the electronic device from a request for the content received from the electronic device. Next, the content provider uses the public address to identify a local caching server (LCS) on a local area network (LAN) to which the electronic device is connected and uses the account identifier to determine that an account associated with the LCS is associated with a group of accounts with which an account for the electronic device is also associated. The content provider then provides a local address of the LCS to the electronic device, which uses the local address to obtain the content from the LCS via the LAN without accessing a content delivery network outside the LAN.

Abstract: A dispersed data storage method for execution by a dispersed storage (DS) unit. In various embodiments, the method begins when the DS unit receives a plurality of encoded data slices and associated metadata. The metadata is interpreted to determine storage instructions regarding the encoded data slices.

In other exemplary embodiments, sequential and/or one-to-many dispersal approaches may be utilized. Further, the DS may employ a variety of criteria to solicit other DS units for storage of encoded data slices.
