.htaccess - fix http to https redirect for DDEV

.htaccess

# Debug trick, uncomment to check values:
# ErrorDocument 404 "Request: %{THE_REQUEST} Referrer: %{HTTP_REFERER}, Host: %{HTTP_HOST}, HTTPS: %{HTTPS}, HTTP:X-Forwarded-Proto: %{HTTP:X-Forwarded-Proto}"
# RewriteRule ^ - [L,R=404]

# The general rule for redirecting HTTP to HTTPS:
# --> Results in "Error too many redirects" in DDEV, because %{HTTPS} is always == off
<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{HTTPS} !=on
  RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>

# Fixed version, check also that HTTP:X-Forward-Proto is off (= http), redirect
# found this via .ddev/apache/apache-site.conf -> https://gist.github.com/nurtext/b6ac07ac7d8c372bc8eb
<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP:X-Forwarded-Proto} !https [NC]
  RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
