Well, what would that return?  I can see having
Session>>respondWithCacheableDocument: and
Session>>respondWithCacheableDocument:seconds:, however.  But that's only
half the problem - caching also requires a constant URL, which the current
methods don't provide.  How do you provide a constant URL for a Form?
The session could keep a cache of the continuation ids assigned to static
documents, although even then you have to make sure to use the same
MIMEDocument instance each time.  So then the interface would become
Session>>urlForDocument: .  I wonder is that also sufficient for images,
css files, etc, taken from disk?

Ramble mode off.
