FWIW, the OpenFlame dev team has developed something inspired by the cute_urls code, with some improvements.
http://github.com/OpenFlame/OpenFlame-F ... andler.phpWith OfUrlHandler->checkExtra() you can also check if there is any other parts to the path specified left
i.e. if you are expecting
http://yoursite/page/somepage/ but not
http://yoursite/page/somepage/someextra ... should404/ then you can use the checkExtra() call to detect that there is another entry for 'someextrastuff' and 'pageshould404' and be able to properly react to it (like, 404'ing because the page specified is invalid)
At the moment, cute_urls does not provide this functionality at all.
There are a few other improvements as well, but I can't think of them off the top of my head.
Also, to note, this is an entirely standalone library file; it is not dependent on the framework it resides in, nor any other system.
