Abstract

A method of post processing a rendered HTML web page includes receiving a rendered web page, parsing the web page to identify resources that the web page includes links to, grouping the identified resources according to a type of resource, creating a resource reference that refers to each group of resources, and inserting the resource reference into the web page to enable the identified resources in the web page to be retrieved.

Claims

1. A method of post processing a rendered HTML web page comprising:

receiving the web page rendered by a server,

parsing the web page to identify mark up language references that refer to resources,

based on the identified mark up language resource references, combining a group of resources according to a type of resource, wherein the type of resource is one of a style sheet, script or image,

creating a resource reference for each group of combined resources, and

inserting the created resource reference into the web page to enable each group of resources referred to in the web page to be retrieved using a single resource request.

2. The method of claim 1 further comprising inserting a single resource reference for each group of resources in the web page.

3. The method of claim 1, wherein the resources are style sheets and the inserted resource reference is a style sheet reference that refers to a group of style sheet resources, the method further comprising:

identifying the location of a first style sheet resource reference in the parsed web page, and

inserting the style sheet reference at that location.

4. The method of claim 1, wherein the resources are scripts and the inserted resource reference is a script reference that refers to a group of script resources, the method further comprising:

determining if the location of a first script resource reference is in a body section of the web page, and upon a positive determination, inserting the script reference at that location, and upon a negative determination, inserting the script reference at the location of a first occurrence of a script resource reference in a head section of the web page.

5. The method of claim 1, wherein the type of resource is a style sheet or script, the method further comprising:

providing a unique resource identification for each resource, and

storing the unique resource identification with the resource reference of the resource.

6. The method of claim 5, wherein the unique resource identification is one of a unique series of numbers, letters or global identifiers.

7. The method of claim 5, further comprising:

including each unique resource identification within the resource reference.

8. The method of claim 1, wherein the type of resource is an image, the method further comprising:

grouping the images for a specific image format into a mosaic image, creating an image style reference that references the mosaic image and defines the images.

9. The method of claim 8, further comprising:

creating a single mosaic image for each image format.

10. The method of claim 8, further comprising:

defining a unique image reference for each image.

11. The method of claim 1, further comprising:

receiving a web page rendered by a web server, wherein the web server intercepted the rendered web page prior to the web page being sent to a web browser.

12. The method of claim 1, further comprising:

receiving the web page rendered by a web application, wherein the web application intercepted the rendered web page prior to the web page being sent to a web server.

13. The method of claim 1 further comprising:

receiving the web page from a web server via a proxy server, where the proxy server has intercepted the rendered web page after the web server has sent the web page to a web browser.

14. The method of claim 1, further comprising:

determining if the identified resource reference refers to an excluded resource.

15. A method of handling a resource request from a web browser, comprising:

receiving the resource request, wherein the resource request includes one or more mark up language resource references, each resource reference referring to a group of resources of one type, wherein the type is one of a style sheet, script or image,

requesting at least two of the resources in the group,

combining the at least two resources, and

sending the combined resources to the web browser.

16. The method of claim 15, further comprising:

determining if the requested resources are stored locally, and, upon a negative determination, retrieving the requested resources and storing the requested resources locally.

17. The method of claim 15, further comprising:

identifying the type of resource in the resource reference, and where the type of resource is identified as a style sheet or script, the method further comprising;

determining unique resource identifications from the resource reference, and

retrieving each identified resource associated with each unique resource identification.

18. The method of claim 17, further comprising:

retrieving each identified resource by resolving the unique resource identification into an individual uniform resource locator associated with the identified resource, and

retrieving the identified resource using the individual uniform resource locator.

19. The method of claim 18, further comprising:

combining all retrieved resources for one type of identified resource.

20. The method of claim 15, further comprising:

identifying the type of resource in the resource reference, and where the type of resource is identified as an image, the method further comprising;

determining a reference to a mosaic image from the resource reference, and

retrieving the mosaic image.
