TEMPORARY CONTENT VERSIONING ON A CLIENT IN A REST-BASED SYSTEM

摘要

Techniques are disclosed for maintaining different versions of a web resource. A client-side application observes and tracks all asynchronous requests for web resources sent from the client to a server. Every time a user attempts to modify a resource on the server, the application stops or otherwise pauses the execution of the request and retrieves a representation of the resource from the server in an original state. The representation is stored locally on the client in a local storage, such as browser persistent storage, and may be stored with a timestamp and the corresponding resource URL. Subsequently, the request to modify the resource is executed. In this manner, a representation of the resource is retained in an original state prior to modification. The locally-stored representation can be used to restore the resource back to the original state in response to a so-called undo request by the user.

主权项

1. A computer-implemented method comprising:
receiving, via a web browser, a first request to change a web resource in a stateless representational state transfer (REST)-compliant software architecture; in response to receiving the first request, retrieving a representation of the web resource in an original state; storing the representation of the web resource in the original state in a storage local to the web browser; changing the web resource to a modified state according to the first request; receiving a second request to restore the web resource to the original state; and in response to receiving the second request, restoring the web resource to the original state based on the stored representation of the web resource in the original state.
