防止网站内容被小偷采集的ASP代码看了一下asp的，因为我的站是静态的所以就凑手写了个静态的javascript版的。
具体就不详细说明了：

<script language="JavaScript">
function setCookie(name, value, expires, path, domain, secure) {
var curCookie = name + "=" + escape(value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "/") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "")
document.cookie=curCookie;
}
function getCookie(name) {
var prefix = name + "="
var cookieStartIndex = document.cookie.indexOf(prefix)
if (cookieStartIndex == -1)
return null
var cookieEndIndex = document.cookie.indexOf(";", cookieStartIndex + prefix.length)
if (cookieEndIndex == -1)
cookieEndIndex = document.cookie.length
return unescape(document.cookie.substring(cookieStartIndex + prefix.length, cookieEndIndex))
}
var now = new Date()
now.setTime(now.getTime() + 6*1000)
var jb51num=10;
var visits = getCookie("jb51")
if (!visits)
visits = 1
else
visits = parseInt(visits) + 1
if (visits>parseInt(jb51num)){
alert('没有内容');
location.href='https://www.jb51.net';
}
setCookie("jb51", visits, now)
</script>
