Never use .* at the beginning or in the middle of a RegEx pattern. It causes hundreds of "back off and retry" trial match attempts.
If the hostname is missing from the index redirect, non-www requests will cause an unwanted double-redirect chain.
Errors in the HOST condition in the non-www rule prevent many non-canonical hostname requests from being properly redirected.
