title: How do you override the sync method for a Backbone collection (as opposed to a model)?
body: <p>I have a folder tree that fetches a collection based on the folder you click. If the user changes his mind and clicks another folder, I want to abort the previous fetch. As this is happens in multiple places within the project, I want to override the sync method on the collection. I've seen so many examples of model syncs, but not for collections. I also want to preserve the query string params. The official documentation states that collections also have a sync method, but I've never seen this done. Please point me in the right direction. Thanks in advance. </p>
