Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for processing image search results. In one aspect, a method includes displaying a page resource received in response to the selection of the image search result in a display environment belonging to a first domain of a server that hosts the page resource, generating an image display environment on the page resource, displaying an image resource referenced by the image search result in the image display environment, and in response to a command to close the image display environment, closing the image display environment and displaying the page resource.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for processing image search results. In one aspect, a method includes rendering a page resource referenced by a selected image search result and received in response to the selection of the image search result in a second display environment to generate a rendered page resource in the second display environment, the second display environment being a display environment that is separate from a first display environment in which the image search results are displayed, generating, from the rendered page resource in the second display environment, an image of the rendered page resource, displaying, in the first display environment, the image of the rendered page resource, and in response to a command navigate to the page resource, transitioning the rendered page resource to the first display environment to display the page resource.

Abstract: Methods, systems, and apparatus for selectively requesting cached versions of resources. In one aspect, a method includes transmitting, by a user device, a resource request for a resource hosted by a first server; determining whether the first server provided response data; in response to determining that the first server provided response data: determining whether a cache request condition has occurred; in response to determining that a cache request condition has occurred: transmitting a request for a cached version of the resource to a cache server; and receiving cache data that causes the user device to display the cached version of the resource; and in response to determining that the first server did not provide response data: transmitting a request for a cached version of the resource to the cache server; and receiving cache data that causes the user device to display the cached version of the resource.
