Ну вот, видимо, Апач на бэкенде и определяет, что это каталог и
возращает его со слэшом:
      Location: http://dynamic.domain.com/data/

Если нужно, что после nginx'а выходил Location: http://www.domain.com/data/,
то нужно поставить

       root  ...
+      proxy_redirect  http://dynamic.domain.com/  /;
       if ...

Непонятно только, почему происходит проксирование.
Файл /var/www/html/data.php существует ?
