Using hosts file on Mac OS X Snow Leopard

Question

I have added two new host entries in

/pricate/etc/hosts

 127.0.0.1/wys/sub-folder local.wys
 127.0.0.1/les/sub-folder local.les

I have flushed the DNS using

dscacheutil -flushcache

I now want to access local.wys and have content served from

localhost/wys/sub-folder

This doesn't work, I have tried 127.0.0.1 and localhost in the hosts file.

Any ideas?

Thanks, Jake
