Hello, I use ispconfig 3.2.7p1 with mutliple servers On my web server, I run Wordpress This wordpress send That's understandable for me: My .htaccess contains Code: <IfModule mod_expires.c> ExpiresActive On ExpiresByType text/css "access 28 days" ExpiresByType text/html "access 28 days" ExpiresByType image/gif "access 28 days" ExpiresByType image/png "access 28 days" ExpiresByType image/jpg "access 28 days" ExpiresByType image/jpeg "access 28 days" ExpiresByType image/webp "access 28 days" ExpiresByType image/x-icon "access 28 days" ExpiresByType application/pdf "access 28 days" ExpiresByType application/javascript "access 28 days" ExpiresByType text/x-javascript "access 28 days" ExpiresByType application/x-shockwave-flash "access 28 days" ExpiresDefault "access 28 days" </IfModule> <IfModule mod_headers.c> <filesMatch "\.(ico|jpe?g|png|gif|webp|swf)$"> Header set Cache-Control "public" </filesMatch> <filesMatch "\.(css)$"> Header set Cache-Control "public" </filesMatch> <filesMatch "\.(js)$"> Header set Cache-Control "private" </filesMatch> <filesMatch "\.(x?html?|php)$"> Header set Cache-Control "private, must-revalidate" </filesMatch> </IfModule> #Disable ETag FileETag None I succeed in removing "no-cache" from header with Code: <?php unset($header['Cache-Control']); ?> in header.php of my wordpress theme but it removes all Cache-Control settings what is not good regarding my .htaccess... I wonder if something inside Apache conf can force "no-cache" I google it but with low success ! For info, I enable that modes Code: a2enmod suexec > /dev/null 2>&1 a2enmod rewrite > /dev/null 2>&1 a2enmod ssl > /dev/null 2>&1 a2enmod actions > /dev/null 2>&1 a2enmod include > /dev/null 2>&1 a2enmod cgi > /dev/null 2>&1 a2enmod dav_fs > /dev/null 2>&1 a2enmod dav > /dev/null 2>&1 a2enmod auth_digest > /dev/null 2>&1 a2enmod fastcgi > /dev/null 2>&1 a2enmod fcgid > /dev/null 2>&1 a2enmod proxy_fcgi > /dev/null 2>&1 a2enmod alias > /dev/null 2>&1 a2enmod headers > /dev/null 2>&1 a2enmod setenvif > /dev/null 2>&1 a2enmod env > /dev/null 2>&1 a2enmod dir > /dev/null 2>&1 a2enmod mime > /dev/null 2>&1 a2enmod proxy > /dev/null 2>&1 a2enmod proxy_http > /dev/null 2>&1 a2enmod proxy_wstunnel > /dev/null 2>&1 a2enmod proxy_html > /dev/null 2>&1 a2enmod remoteip > /dev/null 2>&1 Can you help me to dig with some keyword to look at ?
I may not be exactly clear on what you're wanting, but instead of unsetting this completely, couldn't you just set it to the value you want?
That's obvious... But I have difficulties to code that in PHP Code: <IfModule mod_expires.c> ExpiresActive On ExpiresByType text/css "access 28 days" ExpiresByType text/html "access 28 days" ExpiresByType image/gif "access 28 days" ExpiresByType image/png "access 28 days" ExpiresByType image/jpg "access 28 days" ExpiresByType image/jpeg "access 28 days" ExpiresByType image/webp "access 28 days" ExpiresByType image/x-icon "access 28 days" ExpiresByType application/pdf "access 28 days" ExpiresByType application/javascript "access 28 days" ExpiresByType text/x-javascript "access 28 days" ExpiresByType application/x-shockwave-flash "access 28 days" ExpiresDefault "access 28 days" </IfModule> <IfModule mod_headers.c> <filesMatch "\.(ico|jpe?g|png|gif|webp|swf)$"> Header set Cache-Control "public" </filesMatch> <filesMatch "\.(css)$"> Header set Cache-Control "public" </filesMatch> <filesMatch "\.(js)$"> Header set Cache-Control "private" </filesMatch> <filesMatch "\.(x?html?|php)$"> Header set Cache-Control "private, must-revalidate" </filesMatch> </IfModule> #Disable ETag FileETag None
I set cache control but it is only for html... So, I am back to my first idea : find out from where no-cache is coming ! Is there a possibility to set in php.ini "Cache-control: no-cache" and if yes with which command. It try find on the internet that but I don't
I guess it#s most likle yset by a wordpress plugin, you can find all code and plugins in Wordpress that set a cache control header with this command, run in the web folder of the site: grep -R Cache-Control * | grep /plugins/ to get an idea of which plugins might set it.
WP plugins that typically set such headers are SEO plugins, caching plugins but also security plugins like wordfence set it.
I already did it and found 4 plugins Site health Matomo Webp express Wp optimize I try deactivate them with no success... I will try to remove them and even clean mariadb
It's clear this is WP optimize ! I don't understand, this plugin is setting that .htaccess Code: <IfModule mod_expires.c> ExpiresActive On ExpiresByType text/css "access 28 days" ExpiresByType text/html "access 28 days" ExpiresByType image/gif "access 28 days" ExpiresByType image/png "access 28 days" ExpiresByType image/jpg "access 28 days" ExpiresByType image/jpeg "access 28 days" ExpiresByType image/webp "access 28 days" ExpiresByType image/x-icon "access 28 days" ExpiresByType application/pdf "access 28 days" ExpiresByType application/javascript "access 28 days" ExpiresByType text/x-javascript "access 28 days" ExpiresByType application/x-shockwave-flash "access 28 days" ExpiresDefault "access 28 days" </IfModule> <IfModule mod_headers.c> <filesMatch "\.(ico|jpe?g|png|gif|webp|swf)$"> Header set Cache-Control "public" </filesMatch> <filesMatch "\.(css)$"> Header set Cache-Control "public" </filesMatch> <filesMatch "\.(js)$"> Header set Cache-Control "private" </filesMatch> <filesMatch "\.(x?html?|php)$"> Header set Cache-Control "private, must-revalidate" </filesMatch> </IfModule> #Disable ETag FileETag None and at the same time it is sending : Cache-Control: no-cache ! it looks like a bug, isn't it ?
No, having the two headers Code: Cache-Control: no-cache Cache-Control: private, must-revalidate Is the same as having a single Code: Cache-Control: no-cache, private, must-revalidate
So I dig and find the line in wp-optimize cade that is sending "no-cache" I comment it. I have no more "no-cache" headers. In my .htaccess there is below code for Cache-control I use GTMetrix I understand why ttf files are not cached... But I don't understand why GTmetrix is telling that there is no TTL for css and not saying that for js ? For css, it is private, for js it is public. is there a difference between private and public regarding TTL setting... in both above header set directive there is no "max-age"...
I finally solve my issue. I remove above snipset from .htaccess and decide to move on with a ROBUST software, I mean ISPConfig ! I create snipset in ispc and I push them in concerned vhost ! Thanks a lot for this amazing job you are doing with ispconfig !
