* 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()
|

||||
* content-type:
|
||||
* <code>

* $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.
