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.
