Hi Lee,

Sorry, I don't know how to clear only one part of the cache...
But I think it should be possible to get the updated page without deleting
the cache.
IIRC the cinclude transformer shouldn't do any caching unless it's
explicitely configured to so, see also the section about caching in:
http://cocoon.apache.org/2.1/userdocs/cinclude-transformer.html

Maybe the caching happens in the pipeline which serves the fragments to be
included? Would it be an option for you to set the pipeline to noncaching
(<map:pipeline type="noncaching">) ?

If you find out where exactly the caching happens, it may give you a hint
about what's going wrong.
