내 오징어 캐시는 왜 적중하지 않습니까?

내 오징어 캐시는 왜 적중하지 않습니까?

제가 만든 휴대용 3G/WiFi 라우터에 Squid Cache를 설정했습니다.

프록시는 작동하지만 TCP_MISS만 표시되고 매우 드물게 TCP_MEM_HIT도 표시됩니다.

나는 이것을 이전에 시도한 적이 없습니다. 여기에 내가 생각해낸 구성 파일이 있습니다.

acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
acl localnet src 192.168.99.0/24    
acl SSL_ports port 443
acl Safe_ports port 80      
acl Safe_ports port 21      
acl Safe_ports port 443     
acl Safe_ports port 70      
acl Safe_ports port 210     
acl Safe_ports port 1025-65535  
acl Safe_ports port 280     
acl Safe_ports port 488     
acl Safe_ports port 591     
acl Safe_ports port 777     
acl CONNECT method CONNECT
http_access allow manager
http_access deny !Safe_ports

http_access allow localnet
http_access allow localhost
http_access deny all
http_port 3128

refresh_pattern -i (/cgi-bin/|\?) 0 0%  0
refresh_pattern .       0   20% 4320
cache_mgr *******@*****.com

3G 스틱에 내장된 http 페이지의 파일도 캐시되지 않습니다.

구성 파일에 실수가 있었나요?
/var/spool/squid3을 설정하는 특별한 방법이 있습니까? 방금 sudo mkdir /var/spool/squid3을 사용했고 내부에 모든 비트가 생성되었습니다. 이것은 캐시.log의 출력입니다:

access.log의 두 줄은 다음과 같습니다.

두 개의 서로 다른 시스템, 동일한 파일, 두 개의 누락

두 줄이 더 있는데 이상해요.

1.2.3.9 무엇입니까? 이 URL 중간에 upload.wikimedia.org가 어떻게 위치하나요? 이것은 T-Mobile이 우리와 나머지 네트워크 사이에 유지하는 다른 캐시입니까?
