Webpage correct title, description and image when sharing on facebook

I was sharing a link on facebook and I noticed the title of the page is not correct. Went back to my page, changed my title and still no succes. It seemed facebok was cache-ing this information.
SOLUTION: To remove the cache from Facebook go to this page http://developers.facebook.com/tools/debug and enter your URL.
It would also be helpful to provide special meta tags for facebook on your web page:

<meta property="og:title" content="title" />
<meta property="og:description" content="description" />
<meta property="og:image" content="thumbnail_image" />

More details here: http://developers.facebook.com/docs/share/
