Estou ocupado migrando um projeto de produção do codeigniter para um novo servidor. A configuração atual está funcionando bem há quase um ano, mas ao mudar para a nova pilha LAMP, estou enfrentando um problema estranho ao reescrever o index.php de volta na URL.
Meu pensamento inicial foi que esta questão seria mais adequada para SO, no entanto, o código é exatamente o mesmo entre as duas instâncias e ambas estão executando o Debian 7.5 e o Apache 2.2.22, o que me faz pensar que é uma diferença de configuração do servidor que não conheço de.
Este é o mod_rewrite é o seguinte
RewriteEngine On
RewriteBase /bookings/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
Como eu disse, isso tem funcionado bem na configuração atual, porém no novo servidor os links da página base sempre são reescritos para a mesma página.
Ativei o log de reescrita para ambos os servidores e o novo servidor está executando uma etapa extra de reescrita que não consigo explicar.

Como pode ser visto acima, o novo servidor está fazendo o redirecionamento inicial corretamente, mas há a seção extra que sempre retorna index.php. Alguma ideia do que poderia estar causando isso? Não tenho 100% de certeza de que o problema seja com mod_rewrite. Fiquei sem opções e não sei muito sobre mod_rewrite

Não tenho ideia do que causou isso, mas fiz uma nova imagem do servidor, reinstalei os serviços e o problema desapareceu.
