[quote]All these location like

location /docs.html { rewrite /docs.html /docs/ permanent; }
location /quotes.html { rewrite /quotes.html /docs/quotes.html permanent; }

it's better to change to

location = /docs.html { rewrite ^ /docs/ permanent; }
location = /quotes.html { rewrite ^ /docs/quotes.html permanent; }[/quote]

Done - thanks so much for pointing that out, Igor!
