ionos: Cachify .htaccess for ssl enabled sites

.htaccess

# BEGIN CACHIFY
<IfModule mod_rewrite.c>
# ENGINE ON
RewriteEngine on
RewriteBase /

# set hostname directory
RewriteCond %{HTTPS} on
RewriteRule .* - [E=CACHIFY_HOST:https-%{HTTP_HOST}]
RewriteCond %{HTTPS} off
RewriteRule .* - [E=CACHIFY_HOST:%{HTTP_HOST}]

# set subdirectory
# sometimes %{REQUEST_URI} might be an empty string, so /$ won't match
RewriteCond %{REQUEST_URI} /$
RewriteRule .* - [E=CACHIFY_DIR:%{REQUEST_URI}]
RewriteCond %{REQUEST_URI} ^$
RewriteRule .* - [E=CACHIFY_DIR:/]

# gzip
RewriteRule .* - [E=CACHIFY_SUFFIX:]
<IfModule mod_mime.c>
	RewriteCond %{HTTP:Accept-Encoding} gzip
	RewriteRule .* - [E=CACHIFY_SUFFIX:.gz]
	AddType text/html .gz
	AddEncoding gzip .gz
</IfModule>

# Main Rules
RewriteCond %{THE_REQUEST} !^POST.*
RewriteCond %{QUERY_STRING} ^$
RewriteCond %{REQUEST_URI} !^/(wp-admin|wp-content/cache)/.*
RewriteCond %{HTTP_COOKIE} !(wp-postpass|wordpress_logged_in|comment_author)_
RewriteCond <DOCUMENT_ROOT>/wp-content/cache/cachify/%{ENV:CACHIFY_HOST}%{ENV:CACHIFY_DIR}index.html -f
RewriteRule ^(.*) /wp-content/cache/cachify/%{ENV:CACHIFY_HOST}%{ENV:CACHIFY_DIR}index.html%{ENV:CACHIFY_SUFFIX} [L]
</IfModule>
# END CACHIFY

Update: Seems like some ionos managed servers dont seem to populate %{REQUEST_METHOD} either.

Changed RewriteCond %{REQUEST_METHOD} !=POST to RewriteCond %{THE_REQUEST} !^POST.*
