Abstract

A system for accelerating web page loading in a user client is provided. The system includes computing platform being in communication with the user client and being configured for changing object delivery/loading order or object rendering at the web browser, or bundling the objects into one or more bundles according to object use and change frequency.

Claims

1. A web proxy apparatus comprising a memory comprising programmed instructions stored thereon and a processor coupled to the memory and configured to execute the stored programmed instructions to:

parse source code of a web page retrieved in response to a first request from a client for the web page, wherein the source code comprises a plurality of references each to at least one of a plurality of objects and the first request is received via one or more communication networks;

identify, from two or more of the plurality of references and based on one or more characteristics of each of the plurality of objects, a first subset of two or more of the plurality of objects to include in a first bundle;

obtain the first subset of the plurality of objects from one or more servers and via another one or more of the communication networks, assemble each of the first subset of the plurality of objects into the first bundle comprising a single object having a filename, and store the first bundle in the memory;

modify a subset of the plurality of references of the source code of the web page that correspond to the first subset of the plurality of objects to insert the filename of the single object of the first bundle into a Uniform Resource Locator (URL) of each of the subset of the references;

send the web page with the modified subset of the plurality of references of the source code to the client via the one or more communication networks and in response to the first request;

receive a second request from the client via the one or more communication networks for the first bundle comprising the first subset of the plurality of objects, wherein the second request includes the filename and the first subset of the plurality of objects comprises two or more of the plurality of objects; and

send the first bundle including the subset of the plurality of objects to the client via the one or more communication networks and in response to the second request.

2. The apparatus of claim 1, wherein the first subset of the plurality of objects is identified based on a predicted change frequency of each of the first subset of the plurality of objects.

4. The apparatus of claim 1, wherein the first subset of the plurality of objects are within a visibility area of a window of a web browser and the processor is further configured to execute the stored programmed instructions to modify the source code of the web page to include loading instructions that are configured to cause the web browser to send the second request for the first bundle prior to a third request for a second bundle comprising a second subset of the plurality of objects that are outside the visibility area of the window of the web browser.

5. The apparatus of claim 1, wherein the first bundle is optimized for a cache of the client using at least one of an e-tag or cookie derived information.

6. The apparatus of claim 1, wherein the first subset of the plurality of objects is identified based on whether the first subset of the plurality of objects are common among one or more previously retrieved web pages.

7. The apparatus of claim 1, wherein at least one of the subset of the plurality of references is modified based on a MIME Hypertext Markup Language (MTHML) format or a data Uniform Resource Identifier (URI) format or the first bundle is generated based on a Java Archive (JAR) format.

12. The method of claim 8, wherein the first bundle is optimized for a cache of the client using at least one of an e-tag or cookie derived information.

13. The method of claim 8, wherein the first subset of the plurality of objects is identified based on whether the first subset of the plurality of objects are common among one or more previously retrieved web pages.

14. The method of claim 8, wherein at least one of the subset of the plurality of references is modified based on a MIME Hypertext Markup Language (MTHML) format or a data Uniform Resource Identifier (URI) format or the first bundle is generated based on a Java Archive (JAR) format.

15. A non-transitory computer readable medium having stored thereon instructions for accelerating web page loading comprising machine executable code which when executed by one or more processors, causes the processors to:

parse source code of a web page retrieved in response to a first request from a client for the web page, wherein the source code comprises a plurality of references each to at least one of a plurality of objects and the first request is received via one or more communication networks;
