My environment - CentOS 7, PHP 7.4, Joomla 3.9.28 with enabled native Joomla cache plugin and Global Configuration -> System -> Cache Handler -> File - path /cache
So cache files created under /cache/page/ looks like
d6ce7bd2b5485ba575657fa6cfd878dc-cache-page-2309b00ab41ee13659dcb835b1a1b484.php
as per Joomla documentation "second string of hex digits is a hash of the URL of the site web page, to make the filename unique to that page"
I suppose every cache file has created by native Joomla plugin
/plugins/system/cache/cache.php
But I cannot find a part of code what creates SECOND STRING of HASH in cache file name as above underlined - 2309b00ab41ee13659dcb835b1a1b484
Please, advise - where I could find this part of code ?
(I'd like to write a small improvement to store these unique hash of cache file in MySQL database for my own purposes - but WHAT creates this hash ?
