A computing system includes at least one processor and memory storing instructions executable by the at least one processor, wherein the instructions, when executed, cause the computing system to instruct a synchronization engine to synchronize first and second versions of a file, the first version being stored on a first storage system and the second version being stored on a second storage system, receive a backoff indicator corresponding to the file, based on the backoff indicator, instruct the synchronization engine to backoff synchronizing changes to the file, and allow the changes to the file to be synchronized by a co-authoring application, maintain a first set of collaborative metadata indicative of content of the first version of the file, and maintain a second set of collaborative metadata indicative of content of the second version of the file.

Coordinating file synchronization between a sync engine and another application that supports document collaboration

A synchronization engine detects a notification of a change to a file. It determines whether an application associated with the file has indicated that the file is to be synchronized by the application. If so, the changes to the file are synchronized between a cloud-based storage system and a local disk by the application. Collaborative metadata, associated with the synchronized file, is updated to indicate a state of a copy of the file on the local disk and a copy of the file in the cloud-based storage system. The collaborative metadata is stored by the synchronization engine.

Authenticating internet application sessions. A method includes downloading client side code that when executed implements one or more client side modules including at least one module with message interception functionality. The method includes executing the client side code to implement the one or more client side modules. A request is sent to an internet application server. In response to the request, a message is received from the internet application server indicating that the request is not authorized. The message from the internet application server indicating that the request is not authorized is intercepted at the one or more client side modules. The one or more client side modules, as a result of the message indicating that the request is not authorized, send a request for authentication in a required format for authentication. Authentication is performed without losing user state associated with the request to the internet application server.
