     * WARNING : http_conditional OPTION IS NOT IMPLEMENTED FOR THE MOMENT (TODO)
     *
     * ====> (boolean) debug_header :
     * - if true, a debug text is added before each cached pages
     *
     * ====> (boolean) content_type_memorization :
     * - deprecated => use memorize_headers instead
     * - if the Content-Type header is sent after the cache was started, the
     *   corresponding value can be memorized and replayed when the cache is hit
     *   (if false (default), the frontend doesn't take care of Content-Type header)
     *
     * ====> (array) memorize_headers :
     * - an array of strings corresponding to some HTTP headers name. Listed headers
     *   will be stored with cache datas and "replayed" when the cache is hit
     *
     * ====> (array) default_options :
     * - an associative array of default options :
     *     - (boolean) cache : cache is on by default if true
     *     - (boolean) cacheWithXXXVariables  (XXXX = 'Get', 'Post', 'Session', 'Files' or 'Cookie') :
     *       if true,  cache is still on even if there are some variables in this superglobal array
     *       if false, cache is off if there are some variables in this superglobal array
     *     - (boolean) makeIdWithXXXVariables (XXXX = 'Get', 'Post', 'Session', 'Files' or 'Cookie') :
     *       if true, we have to use the content of this superglobal array to make a cache id
     *       if false, the cache id won't be dependent of the content of this superglobal array
     *     - (int) specific_lifetime : cache specific lifetime
     *                                (false => global lifetime is used, null => infinite lifetime,
     *                                 integer => this lifetime is used), this "lifetime" is probably only
     *                                usefull when used with "regexps" array
     *     - (array) tags : array of tags (strings)
     *     - (int) priority : integer between 0 (very low priority) and 10 (maximum priority) used by
     *                        some particular backends
     *
     * ====> (array) regexps :
     * - an associative array to set options only for some REQUEST_URI
     * - keys are (pcre) regexps
     * - values are associative array with specific options to set if the regexp matchs on $_SERVER['REQUEST_URI']
