If you want an origin server to work with polyclt, the server must
respond with "200 OK" replies to polyclt requests. See RFC 2616 for the
"200 OK" response status definition. An off-the-shelf origin server
will probably reply with "404 Not Found" to every polyclt request
because such a server would try to match URLs in polyclt requests to
local files on server's disks. The match will fail unless you
pre-populate the server's disk space somehow or otherwise make the

This is supported. The PolyMix-2 workload uses the approach you
Note that some OS need to be tuned to support large number of aliases
efficiently. For FreeBSD tuning tips, see

This mode is also supported and used primarily when a single physical
box is not powerful enough to create the desired request stream.
