Abstract

Content rendered for display on a first client device can be referenced for similar pages to be displayed on other client devices such that similar content does not need to be re-rendered. Each client can have a respective virtual rendering engine on a host device, and the content rendered by those virtual engines can be mapped and used to generate content trees for different pages or other groupings of content. When a new page is to be rendered, the tiles or other portions matching previously-rendered tiles can be referenced, so that only new or unique portions need to be rendered for a particular page. The content can come from multiple locations as rendered by multiple virtual clients, such that for many clients the respective virtual engine may not render any content but instead reference rendered content from one or more locations as determined according to the page tree.

Claims20

Dependent claims

A computer-implemented method, comprising:

receiving, at a rendering service including a host computing device, a first request for a first page of content to be provided to a first client device;
rendering, using a first virtual rendering engine executing on the host computing device, the first page of content, the first page of content including a first plurality of tiles, wherein the first plurality of tiles include rendered content;
providing, to the first client device, the first page of content as rendered by the first virtual rendering engine;
receiving, at the rendering service, a second request for a second page of content to be provided to a second client device, the second page of content including a second plurality of tiles, a first subset of the second plurality of tiles including to the same content as a subset of the first plurality of tiles of the first page of content;
causing the content for the first subset of the second plurality of tiles to be provided to the second client device based on the respective rendered content rendered by the first virtual rendering engine for the subset of the first plurality of tiles of the first page of content;
rendering, using a second virtual rendering engine executing on the host computing device, respective rendered content for a remaining subset of the second plurality of tiles;
providing respective rendered content for the remaining subset of the second plurality of tiles to the second client device;
and
updating a tree structure for the first page of content and the second page of content, wherein the first page of content is a parent page of the tree structure and the second page of content is a child page of the tree structure, the child page including references to the same rendered content of the parent page and identifying different content stored for the child page and rendered by the second virtual rendering engine.

6 more elements

A method, comprising:

under control of one or more computer systems having processors configured with executable instructions,
receiving a request for content to be transmitted to a client device;
determining that a first subset of the content has been rendered by a parent virtual rendering engine of a plurality of virtual rendering engines;
providing the first subset of the content to the client device as rendered by the parent virtual rendering engine;
determining that a second subset of the content has yet to be rendered by the plurality of virtual rendering engines;
causing a child virtual engine of the plurality of virtual engines to render the second subset of the content;
providing the second subset of the content to the client device as rendered by the child virtual rendering engine;
and
maintaining a tree structure for a page including the content.

6 more elements

A system, comprising:

at least one processor;
and
memory including instructions that, when executed by the at least one processor, cause the storage device to:
receive a request for content to be transmitted to a client device;
determine that a first subset of the content has been rendered by a first virtual rendering engine of a plurality of virtual rendering engines;
provide the first subset of the content to the client device as rendered by the first virtual rendering engine;
determine that a second subset of the content has yet to be rendered by the plurality of virtual rendering engines;
cause a second virtual engine of the plurality of virtual engines to render the second subset of the content;
provide the second subset of the content to the client device as rendered by the second virtual rendering engine;
and
maintain a tree structure for a page including the content.
