Java/1.4.1_04 使用者代理與一些 jQuery / Javascript 衝突 (404)

自從幾天前我在我的伺服器上放置了一個新的 javascript 文件以來，我收到了奇怪的 404 日誌。似乎某些 Java 使用者代理與 jQuery (1.6.2) 的某些部分發生衝突。每當有人點擊 404 並發送伺服器變數時，我都會發送一封自動電子郵件。

http_user_agentJava/1.4.1_04和 request_uri 如下：

/frontend/js/,data:c,complete:function(a,b,c){c=a.responseText,a.isResolved()&&(a.done(function(a){c=a}),i.html(g?f(

之後直接：

/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 的這兩個部分都可以在縮小的 jQuery 原始碼中找到。這/frontend/js/是我的 javascript 文件的路徑。

我剛剛在 StackOverflow 上閱讀了兩個類似的問題（1和2），但都沒有任何解決方案。我也會在那裡發表評論，但我想知道這裡是否有更多的人有同樣的問題，並解決了它。

有人有線索嗎？

使用者代理與它無關，而且它肯定不會引起問題 - 錯誤的 URL 應該得到 404，這就是這些請求的內容。由於主要解析失敗，這是一些寫得很糟糕的機器人請求一個荒謬的無效路徑（請注意，無效部分都以"字元開始和結束？）。

花點時間嘲笑那個在他們的機器人的 js 解析器上失敗得如此糟糕的傻瓜，然後繼續忽略 404 並繼續你的一天（或者如果你必須阻止那個使用者代理）。

查看我自己的伺服器日誌，我有幾個這樣的條目分佈在幾個星期內，來自幾個不同的 IP 地址。都具有相似但略有不同的使用者代理。

大多數但並非所有 IP 地址似乎都位於羅馬尼亞。

這是我的日誌樣本：

雖然我不相信這個被誤導的機器人會造成任何傷害，但我將遵循此部落格的建議並阻止來自 Java 使用者代理的所有點擊。作為預防措施，您可能希望這樣做。
