Fetching sharded resources from original domain

[GoogleCodeExporter]

What steps will reproduce the problem?
1. ModPagespeedShardDomain example.com s1.cdn.net,s2.cdn.net,s3.cdn.net
2. s*.cdn.net does not have mod_pagespeed installed and just acts as a reverse 
proxy converting all requests for s*.cdn.net/foo -> example.com/foo
3. User requests http://s1.cdn.net/static/mycss.css.ce.asdfasdf.css -> CDN 
requests http://example.com/static/mycss.css.ce.asdfasdf.css -> mod_pagespeed 
cannot find resource because it is being requested on the wrong domain.


This is actually documented behavoir. Specifically, ShardDomain requires that 
the servers you rewrite the domains to point to have mod_pagespeed installed.

However, this seems like a reasonable use-case and we should be able to figure 
out which resource was intended.
