Subject:  rgw: fix the subdir without slash of s3 website url
X-Git-Tag: v12.1.1~127^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=e817e22705ac4f6935cd2b1510446059e69b2499;p=ceph.git

 rgw: fix the subdir without slash of s3 website url

if we use the subdir without slash, we cannot visit the default index.html,
which we configured.It is not consistent with AWS S3.

Fixes: http://tracker.ceph.com/issues/20307
