SOLUTION AT THE BOTTOM
when i click my website .php page details i see the response headers contains:
cache-control public, max-age=2592000
content-type: text/html; charset=utf-8; Cache-control:private
request headers contain:
and that dynamic (.php) page (and whole site) has problem with non refreshing on-page content. like i i do some onsite action that modify database content, but the change is not visible on site, even if i load the page again. I have to use F5 key for change to appear. The page seems to wrongly behave like html, not dynamic.
When i lookup website files for “cache-control”, this is what i see. I also searched for mentioned vlaue “2592000” but found no file to contain it. .htaccess and php.ini does not contain caching related rules per this output). BUT i have suspection that it is inherit from parent folder .htaccess because this script is on subdomain (subfolder of main domain) Main domain .htaccess is here please.
I have seen cloudflare cookie, maybe it is remains from the time i had cloudflar enabled on it. Currently cloudflare is disabled on the DNS record.
Please do you have idea what to try to change?
SOLUTION: It seems that indeed since the site was a subdomain (in subfolder of primary domain) the site got .htacces caching parameters (apache mod_expires) from the parent primary domain directory. When i input same parameters to the child .htaccess, only modified it to cache the content for not 30 days, but just 5 seconds, it started working.
