织梦dedecms做软件站有的缺点 。
就是别人转帖你的下载的时候直接转帖http://www.xxx.com/plus/download.php.........
就是直接打开下载地址列表页这种就可以下载了，耗费资源却又带不了用户。
经过研究，终于搞定了软件频道下载的防盗链，代码发出来大家共享，希望能用的到
改后的功能是
假如软件信息页地址是:/soft/1.htm
下载地址连接是:/plus/download.php?.........
判断来路，
如果不是/soft/1.htm，
直接跳转到/soft/1.htm
如果来路是/soft/1.htm 则展示下载地址
说明下：下边的代码是直接复制我自己站上的，我启用的是全站迅雷下载，打开就自动使用迅雷下载，你也可以做下小修改，不让使用迅雷下载
不使用迅雷的很容易修改：删掉迅雷相关代码,只引用$link就可以了
需要修改的文件为 /plus/download.php
演示:
/do/plus/download.php?open=0&aid=20975&cid=3
必须从/codes/20975.html这个页面进入才正常
