====> (boolean) http_conditional :
- if true, http conditional mode is on
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']
(see default_options for the list of available options)
- if several regexps match the $_SERVER['REQUEST_URI'], only the last one will be used
