HotLink Protection Doesn't Work With IE

i tried to create .htaccess file to protect hotlinking ; it's worked perfect with Firefox but can't work with IE. Here's my .htaccess file:

Code:
RewriteEngine on

<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>
<Limit PUT DELETE>
order deny,allow
deny from all
</Limit>
AuthName domain.com
AuthUserFile www est.htpasswd

RewriteCond %{HTTP_REFERER} !^[url] [NC]
RewriteCond %{HTTP_REFERER} !^[url] [NC]
RewriteCond %{HTTP_REFERER} !^[url] [NC]
RewriteCond %{HTTP_REFERER} !^[url] [NC]
RewriteRule .*.(jpg|jpeg|gif|png|zip)$ [url] [R,NC]

If using Firefox and download a .zip file from my site it'll work but if use Internet Explore it'll only download redirect html file instead.
