[jira] [Comment Edited] (CMIS-818) Navigation services should support Last-Modified/If-Modified-Since Headers

---------------------------------------------------------

I was thinking the LastModifiedObjectInFolderContainerList interface might have a boolean ifModifiedSince() method to indicate the SC_NOT_MODIFIED/OK state and that the service, based on its own SC_NOT_MODIFIED check, would either: a). return an empty list along with ifModifiedSince() equals false if SC_NOT_MODIFIED or b). return a populated list with ifModifiedSince() equals true if OK. This is clearly not as clean as the LastModifiedContentStream handling but seems doable.

> AtomPub and Browser navigation services including getChildren, getFolderTree, getDescendants, and potentially the others should support Last-Modified/If-Modified-Since Headers.
> Some repositories have built-in caching mechanisms to track whether a folder tree has been modified. Since many of the Navigation services often require significant server-side resources, repositories with these built-in caching mechanisms should be able to leverage them with OpenCMIS. Currently, the OpenCMIS NavigationService does not provide hooks to implement such optimizations.
