* Readonly middleware.
*
* It is intercepting all the POST requests with a message telling
* that the website is in read only mode.
*
* Optionally, a message at the top of the page is added to inform
* that the website is in read only mode.
*
* Add the middleware at the top of your middleware list and
* optionally add a message to be displayed in your configuration
* file.
*
* Example:
*
* <pre>
* $cfg['middleware_classes'] = array(
* 'Pluf_Middleware_ReadOnly',
* 'Pluf_Middleware_Csrf',
* 'Pluf_Middleware_Session',
* 'Pluf_Middleware_Translation',
* );
* $cfg['read_only_mode_message'] = 'The server is in read only mode the '
* .'time to be migrated on another host.'
* .'Thank you for your patience.';
* </pre>
*
* You can put HTML in your message.
