> This is a URL normalizer we use that is simple to use and generate for
> dealing with hosts that mix up slash suffixed URL's with non-slash suffixed
> URL's.
> It is similar to the host nomalizer, reducing the number of duplicates while
> crawling. It takes the new line delimited rules, separated by either a
> tabulator or whitespace, followed by a + (PLUS) or - (MINUS) sign denoting
> whether or not a slash is to be added to the path.
> The normalizer ignores pages that look like files with extensions, see tests.
> Note: the normalizer must be enhanced to not take hosts as first argument of
> a rule, but host/path prefixes because some hosts need different rules
> depending on the root path. For example,
> * example.org/cms/news/1/2/3/4 is a CMS that doesn't accept slashes, if they
> are suffixed, the user is redirected to a non-slash page;
> * example.org/files/a/b/ wants to do it just the other way around.
