Foren / Cotonti / Support / Ajax: call for little help

markitup plugin is a good example of AJAX part. markItUp! editor sends data to the AJAX script using POST method and passes the "x" parameter which is equal to $sys['xk']/{PHP.sys.xk}. On the PHP side (ajax part of the plugin) there is nothing special, because Cotonti checks that "x" variable on all POST requests automatically. Manual checks are needed for GET only.
