Subject [jira] [Commented] (CMIS-818) Navigation services should support Last-Modified/If-Modified-Since Headers
Date Fri, 11 Jul 2014 15:16:05 GMT

    [ https://issues.apache.org/jira/browse/CMIS-818?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14058884#comment-14058884

Florian Müller commented on CMIS-818:
-------------------------------------

Please check out [ProgressControlCmisService|https://svn.apache.org/viewvc/chemistry/opencmis/trunk/chemistry-opencmis-commons/chemistry-opencmis-commons-api/src/main/java/org/apache/chemistry/opencmis/commons/server/ProgressControlCmisService.java]
and [AbstractBindingCmisServiceWrapper|https://svn.apache.org/viewvc/chemistry/opencmis/trunk/chemistry-opencmis-server/chemistry-opencmis-server-support/src/main/java/org/apache/chemistry/opencmis/server/support/wrapper/AbstractBindingCmisServiceWrapper.java].
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?

> 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.
