Ok, alguém me ajudou a trabalhar usando:
RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteCond %{THE_REQUEST} !/services/test
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]
RewriteCond %{REQUEST_FILENAME} \.(js|css|gif|jpg|png|swf)$ [OR]
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteCond %{THE_REQUEST} /services/test
RewriteRule ^.*$ index.php [NC,L]
RewriteRule ^.*$ index.php [NC,L]
A regra de reescrita do Zend Framework estava causando um problema, mas está funcionando bem agora.
