Subject: [PATCH] http: Legacy versions of IIS redirect incorrectly
(And newer versions don't seem to like the legacy code). This patch uses a
`Refresh` header for IIS versions prior to 7.0 (included with Windows Vista
/ Server 2008). Starting with IIS 7.0, the Location header should be
properly handled by IIS.
