force pages to end in a slash and rewrite the url

i have to call my pages in this way:

http://example.com/index.php?page=homepage

i want to always show the url in this way

http://example.com/homepage

and at the same time i also want to prevent the insertion of the / at the end of the url...so:

http://example.com/homepage/ or http://example.com/homepage
