Getting forward slashes and hyphins past the taint check

In one of my scripts that I am developing I have a field where the needs 
to supply which my include forward slashes and hyphens.  I understand the 
inherent security risk of allowing such things and so does the taint 
check...  I'm sure the answer to this is really simple and I'm just over 
looking it (or even over complicating things) but here is what I have 
tired to get it to work:

if ( $Cookie_path =~ /^([-\@\w\/\-.]+)$/ ) {
	$Cookie_path = $1;
} else {
	die "Incorrect format";
}
