<hr/><a name="_details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>When a DODS server receives a request from a DODS client, the server CGI script dispatches the request to one of several ``filter'' programs. Each filter is responsible for returning a different aspect of the dataset information: one is for data, one is for the dataset <a class="el" href="classlibdap_1_1DDS.html">DDS</a>, one is for the dataset <a class="el" href="classlibdap_1_1DAS.html" title="Hold attribute data for a DAP2 dataset.">DAS</a>, and a fourth is for a usage message describing the server itself. Some installations may have additional optional filters.</p>
<p>The filter program receives a data request from the dispatch script. It receives its operating parameters from the command line, like any UNIX command, and it returns its output to standard output, which the httpd server packages up into a reply to the client.</p>
<p>This class contains some common functions for the filter programs used to make up the DODS data servers. The filter programs do not <em>have</em> to be called by a CGI program, but that is the normal mechanism by which they are invoked.</p>

<p>Set the CGI/Server version number. Servers use this when answering requests for version information. The version `number' should include both the name of the server (e.g., <code>ff_dods</code>) as well as the version number. Since this information is typically divined by configure, it's up to the executable to poke the correct value in using this method.</p>
<p>Note that the -v switch that this class understands is deprecated since it is usually called by Perl code. It makes more sense to have the actual C++ software set the version string.</p>
