when I fetched some certain sites,I got empty content,contentType,but the fetch status was "fetch_success" and the metadata was sometimes not empty.
how does website configure itself to achieve this? any methods to avoid this situation? I used agent-name: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; MyIE2; .NET CLR 1.1.4322)
