Я занят переносом проекта production codeigniter на новый сервер. Текущая настройка работает нормально уже почти год, но при переходе на новый стек LAMP я столкнулся со странной проблемой с переписыванием index.php обратно в URL.
Сначала я думал, что этот вопрос больше подойдет SO, однако код в обоих случаях абсолютно одинаков, и оба работают под управлением Debian 7.5 и Apache 2.2.22, что наводит меня на мысль, что дело в разнице в конфигурации сервера, о которой я не знаю.
Это mod_rewrite выглядит следующим образом
RewriteEngine On
RewriteBase /bookings/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
Как я уже сказал, в текущей конфигурации это работает нормально, однако на новом сервере ссылки с базовой страницы всегда перезаписываются на ту же страницу.
Я включил ведение журнала перезаписи для обоих серверов, и новый сервер выполняет дополнительный шаг перезаписи, который я не могу объяснить.

Как видно выше, новый сервер правильно выполняет начальное перенаправление, но есть дополнительный раздел, который всегда возвращает index.php. Есть идеи, что может быть причиной этого? Я даже не уверен на 100%, что проблема в mod_rewrite. У меня закончились варианты, и я не знаю много о mod_rewrite
решение1
Понятия не имею, что стало причиной этого, но я переустановил сервер, переустановил службы, и проблема исчезла.
