They allow you to control whether OpenCMIS should stop before it sends a
response. For the AtomPub and the Browser binding you can then send your own
HTTP response.
Does this helps you solving this issue?
> Navigation services should support Last-Modified/If-Modified-Since Headers

> Key: CMIS-818
> URL: https://issues.apache.org/jira/browse/CMIS-818
> Project: Chemistry
> Issue Type: Improvement
> Components: opencmis-server
> Affects Versions: OpenCMIS 0.11.0
> Reporter: Ron Gavlin
> Assignee: Florian Müller
>
> 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.
