CC-2166: Packaging Improvements. Moved the Zend app into airtime_mvc. It is now installed to /var/www/airtime. Storage is now set to /srv/airtime/stor. Utils are now installed to /usr/lib/airtime/utils/. Added install/airtime-dircheck.php as a simple test to see if everything is install/uninstalled correctly.

|
||||
* - 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)
|
