Subject RE: [C2]: Proposal for intermediate output stream
Date Thu, 05 Jul 2001 13:06:35 GMT
> Hi,
> I am currently thinking since some weeks of the following enhancement:
> Creating an intermediate output stream for the response and not directly

+0 from me if it's somehow configurable. Even more desirable for
   only parts of the site.
