Try this..., in this case you needn't any data structure, I think 
$url='http://myurl.com/page.pl?key1=val1&key2=val2&key3=val3';
@value = ("AAA", "BBB", "CCC", "DDD");
for $val (@value)    {
    for (1..3)    {
        $t=$url;
        $t=~s/\bkey$_=val$_\b/key$_=$val/i;
        print $t,$/;
    }
}
