CONFLICT RESOLUTION IN EXTENSION INDUCED MODIFICATIONS TO WEB REQUESTS AND WEB PAGE CONTENT

摘要

A system includes an extension manager configured to cause at least one processor to execute multiple extensions in parallel that each attempt to modify a network request related to a webpage, and a conflict manager. The conflict manager is configured to cause the at least one processor to resolve conflicts among attempts by the multiple extensions to modify the network request. The conflicts are resolved using a set of precedence criteria and conflict rules. The conflict rules include for example logic that specifies that the network request is cancelled if any of the multiple extensions attempt to cancel the request. As another example, if at least two of the multiple extensions attempt to redirect the network request to at least two different URLs, the system determines which one extension is allowed to redirect the network request, and allows only the attempt by the one extension to redirect the network request.
