Windows Live Messenger blocks www.youtube.com (Update) Everything back to normal Windows Live Messenger的座www.youtube.com （更新）一切恢復正常。
Not too long ago, users on the不久以前，用戶對 Neowin.net forums neowin.net論壇 started complaining about開始抱怨 not being able to send YouTube links無法發送的YouTube鏈接 to their contacts on Windows Live Messenger.給他們的聯絡人對Windows Live Messenger的。 I was skeptic at first, but it didn’t take me very long to confirm that is indeed the case.我懷疑在第一，但它沒有考慮我很長的證實，確實如此。
As you can see, any messages that contain in text or links to “www.youtube.com” fails to be delivered.你可以看到，任何郵件包含在文字或鏈接“ www.youtube.com ”未能交付。
Curious as a cat, I loaded up a network packet sniffer to find out exactly what’s going on behind the scenes.好奇，作為一個貓，我裝了一個網絡數據包嗅探器，找出到底是怎麼回事幕後。 Technically, the message packets are in fact sent to the Messenger servers (so it’s not being blocked at your client), but the server sends back a negative acknowledgment (NAK) packet instead of an acknowledgment (ACK) packet.從技術上來說，信息數據包是在事實上，發送到Messenger的服務器（因此它不是被攔截在您的客戶端） ，但服務器發送回的負面承認（洛）數據包，而是一個承認（的ACK ）封包。 Simply speaking, the server is refusing the message.簡單來說，服務器是拒絕的訊息。
As some people may recall, in 2006 there was a正如有些人可能還記得，在2006年有一個 report quoting MSN Sweden admitting報告引述的MSN瑞典承認 Microsoft is “censoring” messages it deems a security threat.微軟是“審查”的訊息它認為是安全威脅。 How it does this is by matching messages with a known list of text strings which are commonly found in phishing and malware sites such as “download.php”.它如何，這是否是由匹配的信息與已知的名單上的文字字串，這是常見的在釣魚式攻擊和惡意軟件的網站，如“ download.php ” 。 Microsoft doesn’t publishes which strings are on this list for obvious reasons, but a comprehensive list of Microsoft不出版，其中字符串在這個清單上出於明顯的原因，但一個全面的名單 known blocked strings can be found here眾所周知，封鎖字符串可以在這裡找到 . 。
We all love a good conspiracy, but I don’t think anyone at Microsoft was dumb enough to do this deliberately to undermine Google.我們都愛一個良好的陰謀，但我不認為任何人在微軟是啞巴不夠為此蓄意破壞的Google 。 On the other hand, even if it was an accident, how do you ever trust this system?在另一方面，即使這是一個意外，你怎麼以往任何時候都相信這個制度呢？
