A Filter should compare the number of bytes received on <tt>FCGI_STDIN</tt>
with <tt>CONTENT_LENGTH</tt> and on <tt>FCGI_DATA</tt>
with <tt>FCGI_DATA_LENGTH</tt>.  If the numbers don't match
and the Filter is a query, the Filter

If the numbers don't match and the Filter is an update, the Filter
should abort the update.<p>
