Abstract

A system loads resources. The system determines to load a module by a web browser, where the module requires a plurality of resources to be synchronously loaded in a specific order. The system asynchronously pre-caches the resources in a browser cache of the web browser and then synchronously loads the resources from the browser cache and according to the specific order. In one embodiment, the system sends a request to a server, where the request is of a request type configured for requesting a first content type, and where the first content type is configured to be pre-cached in the browser cache when received by the web browser. The system then receives content from the server in response to the request, where the content is of a second content type that is different than the first content type, and where the content includes at least one of the resources.

Claims

1. A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to load resources, the loading comprising:

determining to load a module by a web browser, wherein loading the module requires a plurality of resources of a first content type to be synchronously loaded in a specific order;

pre-caching, prior to loading the module, the plurality of resources in a browser cache of the web browser, wherein,

the pre-caching comprises, prior to loading the module, transmitting, from the web browser to a server, at least one request for a second content type that is not executable and receiving, from the server, at least one of the plurality of resources of the first content type in response to the request for the second content type,

the received resource is pre-cached based on the web browser being configured to pre-cache content received in response to requests for the second content type,

the received resource in response to the request for the second content type comprises a browser executable script resource, and the web browser is configured to pre-cache the script resource as a non-executable resource, and

the first content type is different from the second content type; and

loading, after the resources are pre-cached, the module by synchronously loading the plurality of resources in the specific order from the browser cache, wherein synchronously loading the script resource from the browser cache comprises executing, by the web browser, the script resource in accordance with the specific order.

2. The computer readable medium of claim 1, wherein a website that comprises the module is an application development website and the plurality of resources are obtained from an application development server.

3. The computer readable medium of claim 1, wherein content in response to a request for the second content type is configured to be pre-cached in the browser cache when received by the web browser, and in response to the request for the second content type, content of the first content type is received from the server, the content comprising the at least one of the plurality of resources.

4. The computer readable medium of claim 3, wherein a request type for the request for the second content type is selected from among a plurality of request types based on a browser type of the web browser.

5. The computer readable medium of claim 4, wherein the request for the second content type is an image request and the content includes data other than an image, the data comprising the at least one of the plurality of resources.

6. The computer readable medium of claim 4, wherein the request for the second content type is an asynchronous JavaScript and extensible markup language (AJAX) call and the content includes data other than information that is displayed on a webpage.

7. The computer readable medium of claim 4, wherein, based on the browser type, the request for the second content type is a Hypertext Transfer Protocol (HTTP) request and the content includes data in addition to a corresponding HTTP response, the data comprising the at least one of the plurality of resources, wherein the corresponding HTTP response is ignored by the web browser.

8. The computer readable medium of claim 4, wherein, based on the browser type, the request for the second content type is a request for an image pre-fetch or an object pre-fetch, wherein the request is added to a document object model (DOM) that points to the at least one of the plurality of resources, wherein the content includes the at least one of the plurality of resources.

9. The computer readable medium of claim 1, wherein the web browser supports asynchronously downloading the plurality of resources.

10. The computer readable medium of claim 1, wherein,

a current webpage is loaded by the web browser,

at the time of determining to load the module, one or more future webpages after the current webpage are determined based on one or more webpages that have been previously visited by the web browser, and

the module is determined to be loaded when the module is part of at least one of the future webpages.

11. A method of loading resources, comprising:

determining to load a module by a web browser, wherein loading the module requires a plurality of resources of a first content type to be synchronously loaded in a specific order;

pre-caching, prior to loading the module, the plurality of resources in a browser cache of the web browser, wherein,

the pre-caching comprises, prior to loading the module, transmitting, from the web browser to a server, at least one request for a second content type that is not executable and receiving, from the server, at least one of the plurality of resources in response to the request for the second content type,

the received resource is pre-cached based on the web browser being configured to pre-cache content received in response to requests for the second content type,

the received resource in response to the request for the second content type comprises a browser executable script resource, and the web browser is configured to pre-cache the script resource as a non-executable resource, and

the first content type is different from the second content type; and

loading, after the resources are pre-cached, the module by synchronously loading the plurality of resources in the specific order from the browser cache, wherein synchronously loading the script resource from the browser cache comprises executing, by the web browser, the script resource in accordance with the specific order.

12. The method of claim 11, wherein content in response to a request for the second content type is configured to be pre-cached in the browser cache when received by the web browser, and

in response to the request for the second content type, content of the first content type is received from the server, the content comprising at least one of the plurality of resources.

13. The method of claim 12, wherein a request type for the request for the second content type is selected from among a plurality of request types based on a browser type of the web browser.

14. The method of claim 13, wherein the request for the second content type is an image request and the content includes data other than an image, the data comprising the at least one of the plurality of resources.

15. The method of claim 13, wherein the request for the second content type is an asynchronous JavaScript and extensible markup language (AJAX) call and the content includes data other than information that is displayed on a webpage.

16. The method of claim 13, wherein, based on the browser type, the request for the second content type is a Hypertext Transfer Protocol (HTTP) request and the content includes data in addition to a corresponding HTTP response, the data comprising the at least one of the plurality of resources, wherein the corresponding HTTP response is ignored by the web browser.

17. The method of claim 13, wherein, based on the browser type, the request for the second content type is a request for an image pre-fetch or an object pre-fetch, wherein the request is added to a document object model (DOM) that points to the at least one of the plurality of resources, wherein the content includes the at least one of the plurality of resources.

18. The method of claim 11, wherein the synchronously loading is performed after determining that the plurality of resources have been pre-cached.

19. A system for loading resources, comprising:

a processor coupled to storage, that processor executing instructions to;

determine to load a module by a web browser, wherein loading the module requires a plurality of resources of a first content type to be synchronously loaded in a specific order;

pre-cache, prior to loading the module, the plurality of resources in a browser cache of the web browser, wherein,

the pre-caching comprises, prior to loading the module, transmitting, from the web browser to a server, at least one request for a second content type that is not executable and receiving, from the server, at least one of the plurality of resources of the first content type in response to the request for the second content type,

the received resource is pre-cached based on the web browser being configured to pre-cache content received in response to requests for the second content type,

the received resource in response to the request for the second content type comprises a browser executable script resource, and the web browser is configured to pre-cache the script resource as a non-executable resource, and

the first content type is different from the second content type; and

load, after the resources are pre-cached, the module by synchronously loading the plurality of resources in the specific order from the browser cache and according to the specific order, wherein synchronously loading the script resource from the browser cache comprises executing, by the web browser, the script resource in accordance with the specific order.
