如何在不转换为小写的情况下重写php中的url

I want to rewrite my url as the case is. But my rewrite rule just converts it to lower case. My rewrite rule is:

Options -MultiViews
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l

RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

I want mvc.com/Home to be processed. But it is getting convreted to mvc.com/home
