A server generates an image with searchable information from a website and transmits that image to a client device. Since the image may be large, the image is generated and transmitted in the background as the client device browses the website. When the client device requests information from the website, the client device first checks if that information has already been transmitted to it in the image as encoded format. If the client device has this information, which is locally stored, then the client device decodes that portion of the image and retrieves the requested information without ever having to contact the server. If the client device does not have this information stored locally, then the client device contacts the server and retrieves the information. Since the image can contain all of the searchable information of a website, the searching process will become faster as time passes. |

1. A computer-implemented method, comprising:
sending, to a remote source, a first request from a client device for a first portion of content of a set of content; receiving, to the client device, the first portion of content and a data set from the remote source, the data set comprising a plurality of pixel sets, each of the plurality of pixel sets corresponding to a respective portion of content of the set of content; storing the plurality of pixel sets in a cache of the client device as part of a background process; obtaining a second request for a second portion of content of the set of content; determining, from an index on the client device relating portions of content of the set of content to a respective pixel set of the plurality of pixel sets, whether a pixel set of the plurality of pixel sets corresponds to the second portion of content; and retrieving the pixel set from the plurality of pixel sets of the data set from the cache or sending the second request to the remote source for the second portion of content. |
