Web Development

The three core technologies of World Wide Web content production are HTML, CSS, and JavaScript languages.

Browser File Caching

Cache busting with query vars

• Front-end files can be cache-busted in the browser by revving the file URL query string parameter.
• Query string revving will probably support 99% of use cases. If you need to make absolutely sure, use file name revving.
• Cache-busting front-end resources file name revving still necessary

SSL

SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser.

Site-wide redirect for SSL via .htaccess

# BEGIN redirect to https
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
# END redirect to https
