# Phase 1: Blog migration — cytrogen.icu → blog.cytrogen.icu
#
# This is a reference copy of the redirect blocks deployed to /etc/caddy/Caddyfile.
# The production Caddyfile also includes blocks for sourcehut, beszel, freshrss,
# stalwart, etc. — only the realm-relevant portions are shown here.
#
# Status: DEPLOYED 2026-02-27

# Blog now served from /var/www/blog.cytrogen.icu

# 301 permanent redirect — root domain to blog subdomain
cytrogen.icu, www.cytrogen.icu {
	header Link `<https://blog.cytrogen.icu{uri}>; rel="canonical"`
	header X-Robots-Tag "noindex, nofollow"
	redir https://blog.cytrogen.icu{uri} permanent
}

# Phase 4: Replace the redirect block above with:
#
# cytrogen.icu, www.cytrogen.icu {
#     root * /var/www/realm
#     file_server
#     encode gzip
#     try_files {path} {path}/ {path}.html
# }
