.htaccess

# This redirects all users except me to a temporal website.
# Inspired from: https://stackoverflow.com/questions/293285/want-to-redirect-all-visitors-except-for-me
<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  
  # Redirect all except allowed IP
  # The HTTP:X-Forwarded-For is used when the site is behind a proxy or load balancer like CloudFlare, AWS Application Load Balancer, etc.
  # The used ip should be the public ip of your router, use a website like "whats my public ip" to know this.
  # In the case your site isn't behind proxies or load balancer, replace "HTTP:X-Forwarded-For" to "REMOTE_ADDR"
  RewriteCond %{HTTP:X-Forwarded-For} !^169\.169\.169\.169$
  
  # Temporary redirect to this other site.
