Weird behaviour with Content-Location header field

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Crawl "http://www.w3.org/2002/07/owl"

What is the expected output? What do you see instead?

 - "http://www.w3.org/2002/07/owl" has Content-Location of "owl.rdf"
 - context for quads from this document uses <http://www.w3.org/2002/07/owl>
 - a redirect is output from <http://www.w3.org/2002/07/owl> to <http://www.w3.org/2002/07/owl.rdf>

Please use labels and text to provide additional information.

 - behaviour is strange since we now have contexts which are the source of a redirect... there are various dangling redirects now.

(Found through problems ranking BTC11 where links are rewritten according to 
redirects, causing mis-alignment with contexts.)
