How to set up caching?

Question

MODX

I'm constantly having cache issues on my site. Displayed without styles. You need to go to the admin panel and clear the cache, then everything works.
I read this article but did not find clear explanations. How to solve this problem?

Answer 1

I usually configure site caching via .htaccess
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
ServerSignature Off
#AddDefaultCharset UTF-8
php_value upload_max_filesize 32M
php_value post_max_size 10M
php_value default_charset utf-8
php_value max_execution_time 200
AddHandler application/x-httpd-php .html
AddHandler cgi-script .pl .py .jsp .asp .htm .shtml .sh .cgi
AddType application/x-javascript .js
AddType text/css .css
AddType text/xml .xml
AddType application/octet-stream .doc .mov .avi .pdf .xls
# ForceType application/x-httpd-php
AddOutputFilterByType DEFLATE text/html text/plain text/xml application/xml application/xhtml+xml text/css text/javascript application/javascript application/x-javascript

Answer 2

I solved this problem like this
(problem: a site with or without "www" - subsequently the version of the site that was loaded first, that is, which fell into the cache) was correctly displayed)
I simply assign the main domain with www in htaaccess

RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\.mysite\.by [NC]
RewriteRule (.*) www.mysite.by/$1 [R=301,L]
