Столкнулась со следующей проблемой. Неожиданно заменяются пути при внутренних редиректах mod_rewrite.

Сонфигурация virtual host

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot C:/xampp/htdocs/fitbug4
    ServerName local.fitbug4.com

    ErrorLog logs/fitbug4-apache-error.log
        CustomLog logs/fitbug4-apache-access.log common
#    RewriteLog logs/fitbug4-apache-rewrite.log
#    RewriteLogLevel 9
    
    <Directory "C:/xampp/htdocs/fitbug4">

      Order allow,deny
      Allow from all

</VirtualHost>

Часть .htaccess связанная с mod_rewrite:

</IfModule>

Смысл в выборе подходящей закешированной версии, если она существует.

Проблема в том, что посреди серии редиректов изначальный путь дублируется при каждом редиректе и в index.php приходит неверный параметр. Например, вместо health/articles/activity/13 приходит tempquery/gz/tempquery/gz/tempquery/gz/health/articles/activity/13/gz/tempquery/gz/health/articles/activity/13

Поведение на Windows и CentOs аналогично

Эти правила

по несколько раз делают вам реврайт.
Это такая система кэширования?

Нет, реврайта по нескольку раз не получается из-за RewriteCond. Первый RewriteRule сработает, если броузер принимает gzip, второй - если не принимает. Остальные   RewriteCond предотвращают ненужные преобразования к tempquery/* в случае внутренних редиректов. 

А система эта - некая моя модификация Drupal-овского модуля boost
