Too many 400 bad request

[Christopher Meng]

Hi everyone,

I've deployed a server for rsync public mirror,and I use nginx as web
server to display some html for visitors.

Now the problem is, too many 400 errors.

I paste "only a small amount of them" below:

Well,this really make me confused.And I've asked other mirror admins who
use nginx,they all have this problem.

Is it caused by nginx?
Do anyone know the solution?
Thanks.
