Cocoon 2.1 supports an extra attribute in the pipeline, which specifies the expiration header in the http response. This should allow temporary caching of the result. I am not sure where this is documented though.

I just tried out XPathDirectoryGenerator (scratchpad) which essentially does what I need, but is a lot less messy than my initial approach. However, also these results seem not to get cached... Presumably I should save the result with something like a SourceWritingTransformer, and only rebuild the file after explizit request.
