 /**
  * Dynamically execute a subrequest and insert its output in place of the
  * function call.
  *
  * <b>Important Note</b> As with the Midgard Parser, dynamic_load strips a
  * trailing .html from the argument list before actually parsing it.
  *
  * It tries to load the component referenced with the URL $url and executes
  * it as if it was used as primary component. Additional configuration parameters
  * can be appended through the parameter $config.
  *
  * This is only possible if the system is in the Page-Style output phase. It
  * cannot be used within code-init or during the output phase of another
  * component.
  *
  * Example code, executed on a site's homepage, it will load the news listing from
  * the given URL and display it using a substyle of the node style that is assigned
  * to the loaded one:
  *
  * <code>
  * $blog = '/blog/latest/3/';
  * $substyle = 'homepage';
  * midcom::get()->dynamic_load("/midcom-substyle-{$substyle}/{$blog}");
  * </code>
  *
  * Results of dynamic_loads are cached, by default with the system cache strategy
  * but you can specify separate cache strategy for the DL in the config array like so
  * <code>
  * midcom::get()->dynamic_load("/midcom-substyle-{$substyle}/{$newsticker}", array('cache_module_content_caching_strategy' => 'public'))
  * </code>
  *
  * You can use only less specific strategy than the global strategy, ie basically you're limited to 'memberships' and 'public' as
  * values if the global strategy is 'user' and to 'public' the global strategy is 'memberships', failure to adhere to this
  * rule will result to weird cache behavior.
  *
  * @param string $url                The URL, relative to the Midgard Page, that is to be requested.
  * @param Array $config              A key=>value array with any configuration overrides.
  * @return int                       The ID of the newly created context.
