TSUYUSATO Kitsune 55361b3c9a Use 302 to redirect instead of 301
`301` means "Moved Permanently", so browser caches this redirect, it is used when changing server URL.
`302` means "Found", it is used generally (e.g. redirect top page after
login).

Each of `301`, `302`, `303` and `307` means redict, but they are
different. We could choice those status in case.
