Hi,

Try using "$scheme$host$uri$is_args$args" ;)

No, default key isn't calculated from variables...
It's something like: "${proxy_scheme}://$proxy_host$uri$is_args$args"

Also, "$proxy_host" returns whatever you've got in your "proxy_pass"
directive, so in case you've got "proxy_pass http://127.0.0.1:8000" it will
return "127.0.0.1:8000".

See above.

"$request_uri" isn't used in the default cache key.
