<p><code class="code">new cgi_environment ~config ~properties ~input_header out_obj</code>
generates a <a href="Netcgi.cgi_environment-c.html"><code class="code">Netcgi.cgi_environment</code></a> object, from the arguments.
The creation of such an object <i>does not</i> raise any exception.
The method <code class="code">#out_channel</code> of the created environment returns
<code class="code">out_obj</code>.</p>
</div>
</div>
<div class="param_info"><code class="code">config</code> : give the configuration options. Of particular
interest here is <code class="code">config.workarounds</code>. If
<code class="code">`MSIE_Content_type_bug</code> is present, a fix will be applied to
<code class="code">input_header</code>.</div>
<div class="param_info"><code class="code">properties</code> : CGI-like properties as (name, value) pairs.
Examples: <code class="code">("REQUEST_METHOD", "POST")</code>, <code class="code">("SERVER_PROTOCOL",
"HTTP/1.1")</code>. Note that "CONTENT_TYPE" and "CONTENT_LENGTH" are
part of the input header. It is highly recommended to use
<a href="Netcgi_common.html#VALupdate_props_inheader"><code class="code">Netcgi_common.update_props_inheader</code></a> to build this list.</div>
<div class="param_info"><code class="code">input_header</code> : is a list of (field, value) pairs of the HTTP
input request. It is ASSUMED that field names in <code class="code">input_header</code>
are lowercase in order to apply a fix to the MSIE Content-Type
bug. Also remember that the separator is '-', not '_'. Both
requirements will be stafisfied if you use
<a href="Netcgi_common.html#VALupdate_props_inheader"><code class="code">Netcgi_common.update_props_inheader</code></a> to build <code class="code">input_header</code>.
<b>Notes:</b> The header is kept into variables and
<code class="code">#send_output_header</code> sents it directly to <code class="code">out_obj</code>. This has
several advantages:
<ul>
<li>It is possible to change header fields at every moment before
the commitment happens. 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. Example: Assume that the
environment is the web server process (e.g. we are an Apache
module). Typically the header must be stored in different
structures than the body of the message.</li>
