If path value is defined in s3 connection properties this path is used as sumbdomain for server value:

server: example.com
path: mypath

request are made to mypath.example.com.

In s3 emulation for openstack swift old-style calling format is accepted, so properly handled request should look like this:

example.com/mypath

It would be great if we have possibility to choose which calling format want to use.
