As I explained previously in this thread, URLs are generally case-sensitive. The example given in the document (the CakePHP Wikipedia page) only works because someone has gone an installed a redirect page that redirects the all-lowercase version to the correctly-cased version. You can easily demonstrate the case-sensitivity of Wikipedia URLs by trying to access some other case permutation of the URL, such ashttp://en.wikipedia.org/wiki/CAKEphp

For SEO reasons, and for reasons of general sanity, you want only one single URL (e.g. the lowercase one) to be the canonical URL of a resource. So a better solution would be one that occurs before CakePHP's routes (e.g. something in the web server, e.g. mod_rewrite if you're using Apache) and sends all non-canonical versions of a URL to the canonical URL using a 301 Moved Permanent redirect, as already discussed previously in this thread.

$_GET['url']? That's new to me. Is that something CakePHP does? Is there documentation on it?

Even if it does what I think it does, then your suggestion would only address the first part (making URLs work case-insensitively) and would not address the second part (ensuring there is a single canonical URL for each resource and redirecting non-canonical ones to the canonical one).
