 DB Prism CMS uses a different approach to speed up the response time, 
and do not requires Cocoon modifications:
 Here the flow:
    user agent <-- Oracle Web Cache  <-- publishing   <-- DB Prism CMS 
 <-- upload utility   <-- Edit Agent
            |                  (document-v10 compliant)
 |---------------------------------------store             OO upload 
through XSL transformations

 This flows guarantee around 10 second for the first time access to a 
CMS page, and 4ms aprox. for the other access.
  When a user update a document into the CMS repository a trigger 
instaled into PAGES table send an XML post message to Oracle Web Cache 
to signal that this pages was modified and is no longer valid, in the 
next request Oracle Web Cache load a new version from the CMS repository.
  Obviously this CMS includes search engine, versioning, images stored 
into the repository as SVG format inside the Apache document-v10 
compliant documents, and so on.
 Best regards, Marcelo.
