Host an NodeJS app

I created my personnal website with NodeJS in local, it works perfectly. But now, I'd like to host my app on a host. I tried to host on AppFog but it doesn't work, sessions doesn't really work, they sometimes destroy, I don't know where is the issue because they works great in local (the sessions)...

Furthermore, I get an error with the JSDOM module, it doesn't work on AppFog but it works on my local installation of NodeJS (v0.8.15).

The error:

TypeError: Cannot read property 'implementation' of undefined

Where can I host my NodeJS website without issue?
