由于我前几天在服务器上放置了一个新的JavaScript文件，我得到了奇怪的404日志。 看起来，某些Java用户代理与jQuery（1.6.2）的某些部分发生冲突。 我发送一封自动电子邮件，只要有人遇到404，我沿着服务器variables发送。
http_user_agent是Java/1.4.1_04 ，request_uri如下所示：
/frontend/js/,data:c,complete:function(a,b,c){c=a.responseText,a.isResolved()&&(a.done(function(a){c=a}),i.html(g?f(
之后直接：
/frontend/js/]};bf.optgroup=bf.option,bf.tbody=bf.tfoot=bf.colgroup=bf.caption=bf.thead,bf.th=bf.td,f.support.htmlSerialize||(bf._default=[1,
javascript的两个部分都可以在jQuery的精简源代码中find。 /frontend/js/是我的JavaScript文件的path。
我刚刚在StackOverflow（ 1和2 ）上读到了两个类似的问题，但都没有任何解决scheme。 我也会在那里发表评论，但是我想知道是否有更多的人有同样的问题，并解决了这个问题。
任何人有线索？
用户代理与它无关，并且不会造成问题 – 一个错误的URL应该得到一个404，这就是这些请求是什么。 这是一些写得不好的僵尸程序，由于主要的parsing失败，请求一个荒谬无效的path（请注意，无效部分以"字符"开头和结尾）。
花一点时间来嘲笑那些在他们的机器人parsing器上失败的可怜的傻瓜，然后继续忽略这些404s，并随着你的一天继续前进（或者必要时阻止那个用户代理）。
看看我自己的服务器日志，我有几个不同的IP地址分布在几个星期这样的条目。 所有与用户代理类似但略有不同的用户代理。
大多数（但不是全部）IP地址都以罗马尼亚为基地。
以下是我的日志的示例：

虽然我不相信这个被误导的僵尸程序造成了任何伤害，但我将会遵循这个博客的build议并阻止来自Java用户代理的所有命中。 作为预防措施，您可能也想这样做。
