[已解决]宽带下载时自动连接ISP的9203端口，缓存高速下载！

今天，我下载一个软件(http://downloads.sourceforge.net ... yer_0.6.2_setup.exe)，发现通过网页不能下载，就用网际快车下载，当我查看网际快车的日志文件的时候，莫名其妙的一个东西出现在我的面前，“58.17.163.40:9203”，我怎么看这个IP都不是我要下载网站的IP，随即保存了网际快车的日志，下面大家看看。

而我访问的服务器应该是213.203.218.122:80才对，我自己的IP是124.*.*.*,为什么会被ISP劫持这样的下载？难道ISP缓存了所有的下载软件？下面的抓图，大家看！

已解决！！！！！！！！！

经过几次下载分析，发现第一次下载时是连接到远程服务器上，而第二次下载时就自动连接到ISP的缓存服务器上了，然后下载的时候速度就比从远程服务器上下载快了一倍，真是爽啊！大家顶！！！！！！虚惊了一场！！
