如果我了解您，以下代码将解决此问题：

RewriteEngine On

RewriteCond %{HTTPS} =off

RewriteCond %{SCRIPT_FILENAME} !\/index\.php [NC]

#the above line will exclude https://www.hellomysite.com/index.php

# from the following rules

RewriteCond %{SCRIPT_FILENAME} !\/dealers\.php [NC]

# the above line will exclude the https://www.hellomysite.com/dealers.php

# from the following rules

RewriteRule (.+) https://%{HTTP_HOST}/$1 [L,R=301]

# above line will force every pages and directories ,except those who

# excluded above and the main root , to redirect from http to https

# (.+) means not to consider http://www.hellomysite.com/ and if you

# change it by (.*) it will be considered

现在，您可以强制将整个网站从http重定向到https，但www.hellomysite.com和www.hellomysite.com/dealers除外。

注意：在测试上述代码之前，请确保您清空浏览器缓存
