Apakah maksud akses ini??? Ini adalah akses nginx.log

Soalan saya ialah bagaimana CONNECT www.baidu.com melakukan ini?

Juga

Bagaimana ini dilakukan?

Answer 1

Semak ejen. Jika anda mencari "proksi perangkak", akan terdapat banyak alamat pelayan proksi percuma atau berbayar, dan begitulah cara anda akan menemuinya.

Answer 2

Ini adalah format log http://blog.chinaunix.net/uid...

• DAPAT dan POS adalah kaedah permintaan

• /admin/ Alamat sumber yang diminta

• Versi protokol HTTP/1.1 HTTP

• 404 ialah kod status HTTP

• maklumat penyemak imbas ejen pengguna bermula dengan Mozilla/4.0

Boleh dijelaskan dengan membandingkan set log_format
