这个可以实现多服务器分流,可以实现线路自动识别跳转,其原理很简单,无论用户进入你哪个服务器只要你在默认页面使用这个代码,他就会跳转到访问速度最快的服务器,这样可以实现服务器分流,适用于流量大的,有多个线路多个服务器的!
本人经过测试非常好用
代码一:
在要跳转的页面上写上:
Copy code
代码如下:
<script language="JavaScript">
var m=50000;
var n=Math.floor(Math.random()*m+1)
//alert(n);
document.write("<iframe src=http://cnc.jb51.net/test.htm?"+n+"||"+location.search.replace(/\?/g,"")+" WIDTH=0 HEIGHT=0 MARGINHEIGHT=0 MARGINWIDTH=0 FRAMEBORDER=0 SCROLLING=NO></iframe>");
document.write("<iframe src=http://dx.jb51.net/test.htm?"+n+"||"+location.search.replace(/\?/g,"")+" WIDTH=0 HEIGHT=0 MARGINHEIGHT=0 MARGINWIDTH=0 FRAMEBORDER=0 SCROLLING=NO></iframe>");
document.write("<iframe src=http://www.jb51.net/test.htm?"+n+"||"+location.search.replace(/\?/g,"")+" WIDTH=0 HEIGHT=0 MARGINHEIGHT=0 MARGINWIDTH=0 FRAMEBORDER=0 SCROLLING=NO></iframe>");
</script>
--------------------------------------------------------------------------------------
然后写test.htm页面代码:注意每个服务器站点(我上面代码分别为网通,电信,铁通)你自己根据自己站点情况修改里面的网址,这里只是演示,上面网址并不存在,在那几个服务器里面都放下面的test.htm) 都要放这个文件:
Copy code
代码如下:
<script language="JavaScript">
/*
这里写上一些文字,不要太多150-200行就可以了,主要作用是,如果你的站点默认页面为DEFAULT。HTM你把代码一,放上去后他会检测你所有服务器的test.htm,然后读取test.htm文件,寻找最快的页面,哪个访问速度快就进哪个站点,这里要写上文字,就是为了让他来检测读取速度,也不要太少,太少检测不出速度!
*/
if (top.location !== self.location) {
top.location=self.location;
}
var url1,url2;
url1=location.search.replace(/\?/g,"")
url2=url1.split("||");
location.href="index.htm";
</script>
