Simple but Effective

I haven’t tested it extensively, but I am really impressed so far. It looks ultra thin, extra easy, super effective and most importantly really friendly to themes and other plugins. Thank you!

Just letting you know though that locally in debugging mode, the proposed .htaccess settings contain 2 notices:

...
# Mobile gzip
RewriteCond %{HTTP:Cookie} !^.*cache_disable.*$
RewriteCond %{HTTP:Accept-Encoding} gzip
RewriteCond %{HTTP:Cookie} !^.*(wordpress_logged_in_|wp-postpass_).*$
RewriteCond %{HTTP_USER_AGENT} ^.*(

Notice:  Undefined variable: options in C:\xampp\htdocs\wp\36\testbed\wp-content\plugins\lite-cache\options.php on line 327

).*$ [NC]
RewriteCond %{REQUEST_METHOD} !=POST
RewriteCond %{QUERY_STRING} !.+

RewriteCond C:\xampp\htdocs\wp\36\testbed/wp-content/cache/lite-cache%{REQUEST_URI}/index-mobile.html.gz -f
RewriteRule ^(.*) wp-content/cache/lite-cache/$1/index-mobile.html.gz [L]

# Mobile

RewriteCond %{HTTP_USER_AGENT} ^.*(

I haven’t checked it online though.
