Abstract

Cache control for Web application resources can include receiving a cache manifest for a Web application, wherein the cache manifest specifies a Web page of the Web application, and determining, using a processor, a resource that is required by the Web page. A closure collection can be built that includes the resource required by the Web page. A reference to the resource can be written to the cache manifest.

Claims

1. A system, comprising:

at least one processor configured to initiate the following executable operations;

generating a cache manifest for a Web application, the cache manifest specifying a Web page of the Web application;

building a closure collection including a resource required by the Web page;

writing, within the cache manifest, a reference to the resource; and

separating the Web application into;

a first component including the closure collection and the cache manifest and

a second component, distinct from the first component, including a portion of the Web application not included in the first component;

wherein the closure collection comprises at least a first resource and a second resource, and the first resource and the second resource are consolidated into a single, consolidated resource;

wherein the cache manifest is updated based upon the consolidation of the first resource and the second resource.

2. The system of claim 1, wherein

a target specified by the Web page is identified as the resource.

3. The system of claim 1, wherein

the resource is a static resource.

4. The system of claim 1, wherein

each of a plurality of resources included within the closure collection is a static resource.

5. The system of claim 1, wherein

at least a portion of the closure collection is compressed.

6. The system of claim 1, wherein

the first component and the second component are separately deployed.

7. The system of claim 1, wherein

a plurality of references are included within the closure collection, and

a reference is written within the cache manifest for each of the plurality of resources within the closure collection.

8. A computer program product, comprising:

a computer readable storage medium having stored thereon program that, when executed configures a processor to perform the following executable operations;

generating a cache manifest for a Web application, the cache manifest specifying a Web page of the Web application;

building a closure collection including a resource required by the Web page;

writing, within the cache manifest, a reference to the resource; and

separating the Web application into;

a first component including the closure collection and the cache manifest and

a second component, distinct from the first component, including a portion of the Web application not included in the first component;

wherein the closure collection comprises at least a first resource and a second resource, and the first resource and the second resource are consolidated into a single, consolidated resource;

wherein the cache manifest is updated based upon the consolidation of the first resource and the second resource.

9. The computer program product of claim 8, wherein

a target specified by the Web page is identified as the resource.

10. The computer program product of claim 8, wherein

the resource is a static resource.

11. The computer program product of claim 8, wherein

each of a plurality of resources included within the closure collection is a static resource.

12. The computer program product of claim 8, wherein

at least a portion of the closure collection is compressed.

13. The computer program product of claim 8, wherein

the first component and the second component are separately deployed.

14. The computer program product of claim 8, wherein

a plurality of references are included within the closure collection, and

a reference is written within the cache manifest for each of the plurality of resources within the closure collection.
