Important caution
Incorrect .htaccess rules can break a site, create redirect loops, cause 403 errors, or block files. Back up the existing file and test carefully after every change.
.htaccess rule builder
Generate starter .htaccess blocks for static-site canonical rules.
Choose common Apache/cPanel rules for HTTPS, www or non-www, clean index.html redirects, custom 404 handling, security headers, compression, and caching.
