I'm using this module, and it seems to work, if I try to access mypath/ the system redirects me to mypath.
But I notice that on google analytics I obtain two entries for my page, I've both mypath and mypath/.

The percentage is about 10% or less:
/canti/ 23.267
/canti 1.390

What is the problem?

This is an example, I've this beahviour also for many other pages.
