Caching Generator (.htaccess / Nginx)
Images, fonts and scripts don’t need to be reloaded on every visit. With the right cache headers the browser serves them from its own storage, and compression halves the rest. The generator builds the block for your web server.
Caching Generator
Set up browser caching and compression
Pick your server, set the lifetimes, copy the rules. Everything runs in your browser.
Server
Note
- WordPress caching plugins often write these rules themselves already – don't duplicate them.
- Apache: paste the block into
.htaccess– above the# BEGIN WordPressblock.
Your input never leaves the browser. The rules are generated locally via JavaScript.
Everything is generated locally in your browser. Nothing you enter is transmitted to our server.
How it works
- 1 Pick your web server and cache lifetimes per file type
- 2 Enable gzip or brotli
- 3 Paste the block into .htaccess or your Nginx config
