Escape character is ‘^\]’. asdasd HTTP/1.0 400 Bad Request Server: proxygen/129 content-type: text/plain Date: Mon, 09 Jul 2012 15:35:24 GMT Connection: close Content-Length: 42 Error parsing message: invalid HTTP methodConnection closed by foreign host. 作為Linux桌面用戶，在/etc/hosts臨時加上以下一行，暫時解決問題，上facebook也變回暢順。 69.171.224.37 facebook.com www.facebook.com 真正問題的原因有代查明了。 ### 相關文章： 1.
