代理使用什麼魔術？

Question

今天我使用bitvise隧道進行隧道，我設置了監聽代理在Mozilla中。但不幸的隧道工程師沒有意識到代理協議。這裏輸出。

19:45:17.893 Initializing SOCKS/HTTP CONNECT proxy on 127.0.0.1:1080 succeeded.

我不知道這是怎麼回事。所以我決定安裝Proxifier aaaand BINGO！有效！！。這裏使用代理後的輸出：

而在另一種情況下，前幾天我用Mozilla的Privoxy。但不幸的是我使用阻止Facebook頁面的IP。所以我決定再次使用代理商與privoxy鏈接.. aaaand賓果再次..它的工作！

所以，夥計們，你知道在Proxifier中發生了什麼嗎？出於某種原因，我需要在我的Ubuntu桌面中使用此功能:)。請告訴我，如果你知道這件事:)

Answer 1

好吧，謝謝你幫助我，但我已經找到答案bymyself：p ..好吧，它被稱爲代理鏈，代理服務器從一個輸入（2） ）。第一個輸出直接代表我們設置爲代理的代理，第二個輸出來自代理中設置的dns。所以這兩個產生不同的輸出方式。

firefox >> proxifier >>> 1. to dns server >> internet 
         2. to proxyserver we set >> internet 

我來說，這裏的例子： 我使用的Privoxy對HTTP連接添加主機頭，但遺憾的是，因爲有2臺主機在一個請求時，它會做出錯誤的請求。 firefox >> privoxy（帶有兩個主機標頭）===不好請求

所以你需要一些東西來解決問題。是的，它是一個dns支持的代理鏈接應用程序。 火狐>> proxifier >> Privoxy的（有兩個主機頭）===良好請求:)

所以，你需要與DNS服務器鏈接來解決錯誤的請求的DNS支持一些應用..

如果你發現我的意見是錯誤的，請糾正我，因爲這只是我的愚見:) :)
