[project @ Fixed discovery failure due to case-sensitive comparison of 'Location:' header]

If an HTTP redirect was issued during discovery with a 'Location:' header that
doesn't exactly match case (such as 'location:' or 'LOCATION:'), discovery
would fail. This is incorrect behavior per RFC 2616, Section 4.2.

This behavior is corrected by using a case insensitive compare when checking
for HTTP redirects.
