Determining if an Application is Cached

摘要

In general, the subject matter described in this specification can be embodied in methods, systems, and program products for determining if a web application is cached. A source web application that is executed by a web browser that is installed on a computing device determines that the web browser is to navigate to a target web application. The source web application determines whether resources for the target web application are cached at the computing device. The source web application performs actions to request resources for the target web application based on the determination whether resources for the target web application are cached, wherein the actions comprise requesting resources for the target web application using a first address if the target web application is determined to be cached and using a second address if the target web application is determined to not be cached.

1. A computer-implemented method comprising:
determining, by a computing device, that a web browser has received a request to navigate to a target web page using a first address; determining, by the computing device, that the first address includes, at an end of the first address, a first portion that is of a type that the web browser is configured to drop from the first address should the web browser use the first address to send a request to a remote server system for resources that correspond to the target web page; determining, by the computing device in response to having received the request and before requesting the resources that correspond to the target web page, that the resources that correspond to the target web page are not cached at a cache of the computing device; changing, by the computing device, the first address by replacing the first portion at the end of the first address with a second portion in order to generate a second address, wherein the second portion is of a type that the web browser is configured to include in the second address should the web browser use the second address to send a request to the remote server system for the resources that correspond to the target web page; and requesting, by the computing device and in response to having received the request and having determined that the resources that correspond to the target web page are not cached at the cache of the computing device, the resources that correspond to the target web page using the second address instead of the first address.
