Emre,
I find it highly improbable that ALL the sites (including such a high
profile site like google) return invalid redirect header. Please post a
complete HTTP session log (wire/debug log turned on), so I could have a
closer look at what really gets transmitted across the wire and how
HttpClient interprets the response(s).
