/**
 * Adds an HTML meta header./*from w  w  w  .j ava 2  s  .  c  o m*/
 * <p>
 * This method sets either a &quot;name&quot; meta headers, which configures
 * a document property, or a &quot;http-equiv&quot; meta headers, which
 * defines a HTTP headers (but these latter headers are being deprecated).
 * <p>
 * A meta header can however only be added in the following situations:
 * <p>
 * <ul>
 * <li>when a plain HTML session is used (including when the user agent is a
 * bot), you can add meta headers at any time.</li>
 * <li>or, when DOCREF<a class="el"
 * href="overview.html#progressive_bootstrap">progressive bootstrap</a> is
 * used, you can set meta headers for any type of session, from within the
 * application constructor (which corresponds to the initial request).</li>
 * <li>but never for a {@link EntryPointType#WidgetSet} mode application
 * since then the application is hosted within a foreign HTML page.</li>
 * </ul>
 * <p>
 * These situations coincide with {@link WEnvironment#hasAjax()
 * WEnvironment#hasAjax()} returning <code>false</code> (see
 * {@link WApplication#getEnvironment() getEnvironment()}). The reason that
 * it other cases the HTML page has already been rendered, and will not be
 * rerendered since all updates are done dynamically.
 * <p>
 * As an alternative, you can use the &lt;meta-headers&gt; configuration
 * property in the configuration file, which will be applied in all
 * circumstances.
