下面我们来研究这个网站：短美文（http://www.duanmeiwen.com/）
它的robots.txt地址是：http://www.duanmeiwen.com/robots.txt
文件如下：
User-agent: * Disallow: /plus/ad_js.php Disallow: /plus/advancedsearch.php Disallow: /plus/car.php Disallow: /plus/carbuyaction.php Disallow: /plus/shops_buyaction.php Disallow: /plus/erraddsave.php Disallow: /plus/posttocar.php Disallow: /plus/disdls.php Disallow: /plus/feedback_js.php Disallow: /plus/mytag_js.php Disallow: /plus/rss.php Disallow: /plus/search.php Disallow: /plus/recommend.php Disallow: /plus/stow.php Disallow: /plus/count.php Disallow: /include Disallow: /templets
从该文件可以看出它是典型的dedecms的robots，因此初步去顶短美文使用的是dedecms系统。
