A computer-implemented method and system for prerendering web content are described. A computing device determines a navigation event within a web browser based at least in part on a prerender tag embedded within a web page. The prerender tag includes a ranking value used to rank links to prerender and a time parameter. The computing device requests content associated with the navigation event and prerenders the content associated with the navigation event in an alternate instance of the web browser that is hidden from a user of the web browser. The computing device determines whether the user has selected the navigation event within a time period based on the time parameter associated with the prerender tag. The alternate instance of the web browser containing the prerendered content in a current user instance of the web browser may be displayed. The computing device may discard the prerendered content.

Methods for prerendering and methods for managing and configuring prerendering operations

A method and system for improving access to network content are described. Aspects of the disclosure minimize the delay between a navigation event and a network response by prerendering the next navigation event. For example, the method and system may predict a likely next uniform resource locator during web browsing to preemptively request content from the network before the user selects the corresponding link on a web page. The methods and systems describe a variety of manners for prerendering content and managing and configuring prerendering operations.

Access to network content

Aspects of the disclosure provide a system and method for prerendering of search result pages. A search engine may process search queries received from a client. The search engine may determine one or more search results in response to the search query. One or more of the search results may be associated with prerender instructions, such that when the search results are received by the client, the client prerenders the search results associated with the prerender instructions. Prerender instructions may be associated with the search results in various manners, including ranking the search results based on relevance, or ranking the search results based on the likelihood of selection. Metrics and analytical data may be collected from the client to improve the search result prerendering process.

System and method for improving access to search results

Systems and methods for resolving a request associated with a host expression to an Internet Protocol (IP) address are provided. In some aspects, a request for content from a content server is transmitted from a client computing device. The request is associated with a host expression of the content server. A message including the requested content and an indication of an Internet Protocol (IP) address set of a DNS resolution of the host expression of the content server is received in response to the request. The requested content includes text or an image. The IP address set of the DNS resolution of the host expression of the content server is stored in a local memory of the client computing device. The IP address set is stored for resolution of future requests associated with the host expression of the content server locally at the client computing device.

Resolving a host expression to an internet protocol address

A method and system for improving access to network content are described. Aspects of the disclosure minimize the delay between a navigation event and a network response by prerendering the next navigation event. For example, the method and system may predict a likely next uniform resource locator during web browsing to preemptively request content from the network before the user selects the corresponding link on a web page, where the network content includes a second portion including an advertisement and a first portion that does not include the advertisement. Responsive to the request, the first portion of the network content is provided without the second content. When a user selects a navigation event associated with the network content, the second portion for display is provided to the user with the first portion. The methods and systems describe a variety of manners for prerendering content and managing and configuring prerendering operations.

A system and method provide server side support for seamless, scalable rewind and playback of a video stream. A video stream is stored and indexed in a network storage place. A video stream can be indexed at frame level where each intra frame of the video stream has an index indicating the file offset and the time stamp of the intra frame in the video stream. A user request for rewinding of a video stream while the video stream is being broadcast is processed by extracting the rewinding time requirement from the user request. The extracted rewinding time value is used to calculate the requested file offset. The video stream starting at the requested time is retrieved and played back according to the user request. The system also provides server side support for seamless rewinding of a video stream and scalable system performance across multiple streaming data centers.

Server-side support for seamless rewind and playback of video streaming

Aspects of the disclosure minimize the delay between a navigation event and a network response by prerendering the next navigation event. The methods and systems described herein may predict a likely next uniform resource locator during web browsing to preemptively request network content from the network before the user selects the corresponding link on a web page. In one aspect, a subset of content from the network content is redacted in order to create a set of partial content such that the set of partial content comprises the network content with the redacted content removed. One or more hypertext transfer protocol (HTTP) error codes within the set of partial content is inserted in place of the redacted content. When notification is received that the set of partial content is accessed by a user device, the redacted content is sent in response.
