Thanks for the suggestion.

But I think that user agent and referer field might not be the major issue.
I used wget on the same URL without addtional arguments like user agent
or referer url, it could get correct
response from server and redirect to the desired URL. Here's the log:

[root_at_ykhuang] # wget -S
