.htaccess 500 erro interno do servidor, sinalizador incorreto

Question

Gostaria de adicionar o seguinte ao meu arquivo .htaccess do Magento:

RewriteBase /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9} /index.php HTTP/
RewriteRule ^index.php$ http://www.mystore.com/ [R=301,L]

No entanto, é um erro de 500 servidores internos.

Um exame de registro resulta em:

RewriteCond: bad flag delimiters

Existe uma maneira de ter isso reescrito ou para solucionar problemas de alguma forma?

EDIT: Meu arquivo htaccess atual:

Answer 1

O problema está aqui:

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9} /index.php HTTP/

A separação de espaço significa que apenas ^[A-Z]{3,9} é considerado parte da regex (e o restante é tratado como uma flag - o que não funciona bem, como você encontrou).

Você precisaria envolvê-lo entre aspas:

RewriteCond %{THE_REQUEST} "^[A-Z]{3,9} /index\.php HTTP/"

Ou melhor ainda, basta usar um equivalente com uma sequência de correspondência menos meticulosa.

RewriteCond %{REQUEST_URI} ^/index\.php$
