Abstract

Web page loading time may be decreased with the use of a page-maintained storage cache on a client device. In various implementations, a server may receive a request for a web page from a web browser that is on the client device. The server may provide a chunk reassembler to the client device that determines whether any chunks in the web page are already stored on the client device. Subsequently, the server may send one or more chunk of the web page to the client device when the chunk reassembler determines that the one or more chunks of the web page are missing from the client device. The chunk reassembler may then instruct the web browser to assemble the one or more received chunks with the one or more chunks that are stored on the client device into the web page for presentation on the client device.

Claims

1. A computer-readable memory storing computer-executable instructions that, when executed, cause one or more processors to perform operations comprising:

receiving a request for a web page from a web browser of a client device and a cookie;

in response to receiving the cookie and the cookie including an indicator indicating every portion of a plurality of portions of the web page are stored on the client device, sending a reassembler instructing the web browser to assemble at least some portions of the plurality of portions that are stored on the client device into the web page for presentation on the client device;

in response to receiving the cookie and the cookie including the indicator indicating one or more portions of the plurality of portions of the web page are stored on the client device and determining that at least one portion of the plurality of portions of the web page is missing from the client device, sending the at least one portion and the reassembler to the client device, the reassembler instructing the web browser to combine the at least one portion with the one or more of the portions that are stored on the client device into the web page for presentation on the client device; and

in response to receiving the cookie and the cookie not including the indicator, sending an annotated version of the web page and the reassembler to the client device for presentation on the client device.

2. The computer-readable memory of claim 1, the operations further comprising inlining one or more objects into HTML coding of the web page and dividing the web page into the plurality of portions prior to or upon receiving the request for the web page, the one or more objects including at least one of a script, a style sheet, or another text-based object.

3. The computer-readable memory of claim 2, the operations further comprising:

assigning a unique identifier to each portion of the plurality of portions of the web page;

in response to receiving the cookie and the cookie including the indicator indicating that the one or more portions are stored on the client device and identifiers of the one or more portions that are stored on the client device, comparing the identifiers of the one or more portions that are stored on the client device with the unique identifier to each portion of the plurality of portions of the web page; and

identifying the at least one portion of the plurality of portions of the web page that is missing from the client device.

4. The computer-readable memory of claim 3, wherein the assigning includes assigning a hash of data in a particular portion of the plurality of portions as an unique identifier to the particular portion, a globally unique identifier (GUID) to the particular portion, or a strictly increasing identifier to the particular portion.

5. The computer-readable memory of claim 2, wherein the dividing of the web page into the plurality of portions includes dividing the web page into content-delimited portions using Rabin hash values.

6. The computer-readable memory of claim 2, wherein the dividing of the web page into the plurality of portions includes dividing the web page into the plurality of portions based on a predetermined size limitation for individual portions of the plurality of portions or a data structure of the web page, or dividing the web page to encapsulate the script or the style sheet in a portion of the plurality of portions.

7. The computer-readable memory of claim 1, wherein the reassembler is a JavaScript application.

8. The computer-readable memory of claim 1, wherein the sending the at least one portion and the reassembler includes sending the at least one portion to the client device as a delimited HTML string for substring extraction into the at least one portion by the reassembler.

9. The computer-readable memory of claim 1, wherein the annotated version of the web page comprises inlined HTML that includes one or more inlined objects and a manifest that is used by the reassembler to parse the inlined HTML into the plurality of portions subsequent to a display of the annotated version of the web page on the client device.

10. The computer-readable memory of claim 1, the operations further comprising, prior to receiving, at the server, the request for the web page, determining whether the one or more portions are stored in a document object model (DOM) storage of the web browser on the client device.

11. The computer-readable memory of claim 1, wherein a portion of the plurality of portions of the web page comprises a chunk of the web page.

12. A method, comprising:

receiving, at a server, a request for a web page and a cookie from a web browser that is on a client device;

in response to the cookie indicating to the server that no chunks of the web page are stored on the client device, sending an annotated version of the web page and a chunk reassembler from the server to the client device, the chunk reassembler to parse inlined Hypertext Markup Language (HTML) of the annotated version into chunks according to a chunk manifest in the annotated version;

in response to an indicator stored on the cookie indicating to the server that all of the chunks of the web page are stored on the client device, sending at least the chunk reassembler from the server to the client device, the chunk reassembler to instruct the web browser to assemble the chunks of the web page for presentation on the client device; and

in response to the indicator stored on the cookie indicating that at least one chunk of the chunks of the web page that are stored on the client device is missing from the client device, sending the at least one chunk and the chunk reassembler to the client device, the chunk reassembler instructing the web browser to assemble the at least one chunk with one or more of the chunks of the web page that are stored on the client device into the web page for presentation on the client device.

13. The method of claim 12, wherein the inlined HTML comprises one or more inlined objects, and the one or more inlined objects includes at least one of a script, style sheet, or another text-based object.

14. The method of claim 12, wherein the chunk reassembler is to further instruct the web browser to display the inlined HTML in the annotated version of the web page prior to the parse of the inlined HTML of the annotated version of the web page into the chunks.

15. The method of claim 12, wherein the chunk reassembler is to further store the chunks into a document object model (DOM) storage of the web browser.

16. The method of claim 12, wherein the cookie further includes a list of individual chunks of the chunks of the web page that are stored on the client device.

17. A server, comprising:

one or more processors; and

a memory that includes components that are executable by the one or more processors to perform actions comprising;

inlining one or more objects into Hypertext Markup Language (HTML) of a web page, the one or more objects including at least one of a script or a style sheet;

dividing the web page into a plurality of portions and assigning an unique identifier to each portion of the plurality of portions;

receiving a cookie from a web browser;

in response to an indicator associated with the cookie indicating that every portion of the plurality of portions of the web page is stored on a client device, sending at least a reassembler instructing the web browser to assemble at least some of the plurality of portions that are stored on the client device into the web page for presentation on the client device;

in response to the indicator associated with the cookie indicating that one or more portions of the plurality of portions of the web page are stored on the client device and that at least one portion of the plurality of portions of the web page is missing from the client device, sending the at least one portion and a reassembler from the server to a client device, the reassembler following arrival at the client device instructing the web browser on the client device to assemble the at least one portion with the one or more portions that are stored on the client device into the web page for presentation on the client device; and

in response to the cookie not including the indicator and indicating that none of the portions of the plurality of portions of the web page are stored on the client device, sending an annotated version of the web page and the reassembler to the client device for presentation on the client device.

18. The server of claim 17, wherein the cookie from the web browser includes identifiers of the one or more portions that are stored on the client device.

19. The server of claim 18, wherein the actions further comprise determining the one or more portions that are stored on the client device by comparing the one or more identifiers in the cookie to an index of identifiers for the plurality of portions of the web page.

20. The server of claim 17, wherein in response to the cookie not including the indicator, the reassembler instructing the web browser to display inlined HTML of the annotated version at the client device, and parsing the inlined HTML into the plurality of portions according to a manifest in the annotated version at the client device.
