redirect problem with ?tmpl=component

Hi and thank you about the help.
I use template Biz
My web site: www.around-naples.com
I have problem with this kind of redirect.
On my .htaccess I put this line:
redirect 301 /en/royal-palace-of-caserta.html?tmpl=component /en/royal-palace-of-caserta.html
but the redirect doesn't work.

There are other pages like this index on google
Any suggest?
thank you
Tony

Hello, this redirect will never work
The component is not an url extension.
Google what ?tmpl=component is and what it do

google duplicate the content
www.around-naples.com/en/royal-palace-of....html?tmpl=component

the correct one is : www.around-naples.com/en/royal-palace-of-caserta.html

How do I have to do?

No way to remove all links with ?tmpl=component ?

for example:
www.around-naples.com/en/royal-palace-of....html?tmpl=component
this page is blank Google will be index this page with error...
