1) Is it possible with .htaccess to rewrite all of your URLs to just http://example.com
?
E.g.:
http://example.com/folder/subfolder/file.php
->http://example.com
http://example.com/index.php
->http://example.com
http://example.com/folder/file.php?foo=bar&baz=qux
->http://example.com
2) If it is possible, how would this effect SEO and page rankings?
