Howdy,
So tomcat provides a temporary directory per-cotnext accessible via
javax.servlet.context.tempdir per the 2.3 Servlet Specification.  No
problem there.

I don't think the spec (including the 2.4 PFD version) says anything
about cleaning up the temporary directory.  Does tomcat provide any
mechanisms for administrative cleanup (e.g. via the manager app) of the
temporary directories?  Does tomcat provide any mechanism, e.g. a
configuration parameter on the <Context> tag, for automatic cleanup of
the temporary directory when the context is shut down?  Does anyone
think these things would be useful?

My current scenario is a webapp that needs to write temporary files
(intermediate things in large scientific calculations) to disk.  I write
them to the context temporary directory.  One part of the cronjob that
periodically (weekly) restarts tomcat cleans up the tempdir.  This works
fine, but I'm wondering if there's a better way.

Any ideas, opinions, etc. will be appreciated.  If people think it's
useful, I could write and contribute some code to implement one or more
of the above in tomcat 4.1.x / 5.x.  Thanks,
