原本路径是http://localhost:7737/websennet/Shops/index.aspx?LoginName=webssss,需要转换后的为http://localhost:7737/Shop/index/webssss.aspx。是不是这样写
<RewriterRule>
        <LookFor>
          ~/Shop/index/([a-zA-Z0-9]).aspx$
        </LookFor>
        <SendTo>
          ~/Shops/index.aspx?LoginName=$1
        </SendTo>        
      </RewriterRule>
