[project @ 2004-02-05 00:11:35 by paulb]
Added support for BaseHTTPRequestHandler transactions.
Added a commit method for transactions, since some frameworks do not
provide support for ad-hoc definition of response information; WebStack
must therefore make sure that responses are defined correctly after
potentially receiving response information in an order unsuitable for the
underlying framework.
All adapters should call commit on transactions.
