The
environment <code class="code">#out_channel</code> is wrapped into a transactional channel
or a discarding channel according to <code class="code">op</code> (<code class="code">`Direct</code> or
<code class="code">`Transactional</code>) and <code class="code">request_method</code> (<code class="code">`HEAD</code> requests must only
return a header). For standard cases, when POST and PUT arguments
are available through a <code class="code">Netchannels.in_obj_channel</code>, we recommend
you use <a href="Netcgi_common.html#VALcgi_with_args"><code class="code">Netcgi_common.cgi_with_args</code></a> that will parse the
arguments for you and check preconditions.
<p>
Remark: You may think that the argument <code class="code">meth</code> is superfluous as
it can be deduced from <code class="code">env#cgi_request_method</code>. While it is true
for <code class="code">`DELETE</code>, <code class="code">`GET</code>, <code class="code">`HEAD</code> and <code class="code">`POST</code>, the <code class="code">`PUT</code> takes a
<a href="Netcgi_common.cgi_argument.html"><code class="code">Netcgi_common.cgi_argument</code></a> parameter. Setting correctly this
parameter and decoding <code class="code">env#cgi_request_method</code> is done for you by
<a href="Netcgi_common.html#VALcgi_with_args"><code class="code">Netcgi_common.cgi_with_args</code></a>.<br>
