 /**
  * Serve a request for a minified file. 
  * 
  * Here are the available options and defaults:
  * 
  * 'isPublic' : send "public" instead of "private" in Cache-Control 
  * headers, allowing shared caches to cache the output. (default true)
  * 
  * 'quiet' : set to true to have serve() return an array rather than sending
  * any headers/output (default false)
  * 
  * 'encodeOutput' : set to false to disable content encoding, and not send
  * the Vary header (default true)
  * 
  * 'encodeMethod' : generally you should let this be determined by 
  * HTTP_Encoder (leave null), but you can force a particular encoding
  * to be returned, by setting this to 'gzip' or '' (no encoding)
  * 
  * 'encodeLevel' : level of encoding compression (0 to 9, default 9)
  * 
  * 'contentTypeCharset' : appended to the Content-Type header sent. Set to a falsey
  * value to remove. (default 'utf-8')  
  * 
  * 'maxAge' : set this to the number of seconds the client should use its cache
  * before revalidating with the server. This sets Cache-Control: max-age and the
  * Expires header. Unlike the old 'setExpires' setting, this setting will NOT
  * prevent conditional GETs. Note this has nothing to do with server-side caching.
  * 
  * 'rewriteCssUris' : If true, serve() will automatically set the 'currentDir'
  * minifier option to enable URI rewriting in CSS files (default true)
  * 
  * 'bubbleCssImports' : If true, all @import declarations in combined CSS
  * files will be move to the top. Note this may alter effective CSS values
  * due to a change in order. (default false)
  * 
  * 'debug' : set to true to minify all sources with the 'Lines' controller, which
  * eases the debugging of combined files. This also prevents 304 responses.
  * @see Minify_Lines::minify()
  *
  * 'concatOnly' : set to true to disable minification and simply concatenate the files.
  * For JS, no minifier will be used. For CSS, only URI rewriting is still performed.
  * 
  * 'minifiers' : to override Minify's default choice of minifier function for 
  * a particular content-type, specify your callback under the key of the 
  * content-type:
  * <code>
  * // call customCssMinifier($css) for all CSS minification
  * $options['minifiers'][Minify::TYPE_CSS] = 'customCssMinifier';
  * 
  * // don't minify Javascript at all
  * $options['minifiers'][Minify::TYPE_JS] = '';
  * </code>
  * 
  * 'minifierOptions' : to send options to the minifier function, specify your options
  * under the key of the content-type. E.g. To send the CSS minifier an option: 
  * <code>
  * // give CSS minifier array('optionName' => 'optionValue') as 2nd argument 
  * $options['minifierOptions'][Minify::TYPE_CSS]['optionName'] = 'optionValue';
  * </code>
  * 
  * 'contentType' : (optional) this is only needed if your file extension is not 
  * js/css/html. The given content-type will be sent regardless of source file
  * extension, so this should not be used in a Groups config with other
  * Javascript/CSS files.
  *
  * 'importWarning' : serve() will check CSS files for @import declarations that
  * appear too late in the combined stylesheet. If found, serve() will prepend
  * the output with this warning. To disable this, set this option to empty string.
  * 
  * Any controller options are documented in that controller's createConfiguration() method.
  * 
  * @param Minify_ControllerInterface $controller instance of subclass of Minify_Controller_Base
  * 
  * @param array                      $options    controller/serve options
  * 
  * @return null|array if the 'quiet' option is set to true, an array
  * with keys "success" (bool), "statusCode" (int), "content" (string), and
  * "headers" (array).
  *
  * @throws Exception
