I have had problems using rewrite in this way. The URL that rewrite analyses may have already been changed by `index` or some other command, and this will lead to redirect loops. To avoid that problem, I have used: if ($request_uri ~* "^(.*)\.html?$") { return 301 $1; } The above is a safe use of "if", and can be helpful since it operates on the actual uri, not the internal uri.
