摘要： Techniques to update a web application are described. A method includes receiving an application update request for a requested web application from a service worker web application executing in a web browser on a client device, the application update request comprising a cached version indicator for a local cached copy of the requested web application on the client device; determining whether an updated requested web application is available based on the cached version indicator. When the cached version indicator is less than a current version indicator, an archived copy of the previous version of the requested web application indicated by the cached version indicator and a current copy of the current version of the requested web application are retrieved, and a delta update is generated based on the archived copy and current copy. The delta update is sent to the service worker web application. Other embodiments are described and claimed.
