Subject: [PATCH] MINOR: stats: send content-length with the redirect to allow
 keep-alive

After a POST on the stats admin page, a 303 is emitted. Unfortunately
this 303 doesn't contain a content-length, which forces the connection
to be closed and reopened. Let's simply add a content-length: 0 to solve
this.
