Magento: How to create new URL with slashes (folders)?
===

I'm using magento 1.7.0.2 and I have an [extension][1] that requires me to set up to URLs:

    http://www.yourstore.com/pagseguro/pay/success/

This url will be used from a third party to API to redirect back to my site. I'm unable to set it up. 

I tried to set up a CMS page, but it does not seem to work with any slashes. I was able to set up a `pagseguro` as the key URL in a CMS page, but whenever I try `pagseguro/pay/success/` as the key URL or even `pagseguro/` , it does not work.

How can I achieve this? I have "Use web server rewrite" enables, but even disabling it, it does not work. Thanks
