For example, it is possible to set the content-length field which is normally only known just at the time of the commit operation.</li> </ul> <ul> <li>The <code class="code">environment</code> object can process the header; for example it can fix header fields.</li> </ul> <ul> <li>It is simpler to connect to environments which transport the header in non-standard ways.
