edit upload .cast file url

[v1xingyue]

Some http servers such as nginx, will return a 301 redirect , when you post to a url not ended with / .

When Post To /asciinema/api/asciicasts ,
It will return :
301 /asciinema/api/asciicasts/ ,

Thanks, however, for the ones which don't redirect and don't handle path with and without trailing slash the same it could also break upload. asciinema-server handles the one without slash just fine. What kind of setup you have where this doesn't work today? I don't think Nginx will do the redirect when using upstream directive unless it's explicitly told so.
