[web] use a redirect for /data/foo requests that don't use the instance md5 hash
The actual file contents can be cached for a long time. If the request
doesn't use the hash, that's wrong. Using a redirect lets keep the
caching for the actual file contents while not breaking requests missing
the hash.
