Document Preview Caching

[chicks]

How does one turn off caching of the preview, without slowing down normal web viewing?

Preview a document.  Edit the document, check it back in.  Preview it again.  You'll see the un-edited document in the preview, not good.

Is there a way to tell the Flash viewer to NOT cache the documents?  I've tried setting its allowed storage to zero, but it does no good.

Try to add this code to file C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\classes\alfresco\templates\webscripts\org\alfresco\repository\upload\upload.post.js at line 240:

// remove preview
var thumbnails = updateNode.getThumbnails();
   
if (thumbnails.length > 0) {
for (i = 0; i < thumbnails.length; i++) {
  thumbnails[i].remove();
}

The idea is to clean preview cache objects just after upload new file version.
