简单的 web 代理。在 linux 上可以使用 squid。本文记录 squid 的配置。
让项目运行在一个独立的局部的 Python 环境中，使采用不同环境的项目互不干扰。

默认配置
squid 功能很强大，默认配置/etc/squid/squid.conf很长。去除注释掉的行，仅剩：
acl localnet src 0.0.0.1-0.255.255.255 # RFC 1122 "this" network (LAN)
acl localnet src 10.0.0.0/8 # RFC 1918 local private network (LAN)
acl localnet src 100.64.0.0/10 # RFC 6598 shared address space (CGN)
acl localnet src 169.254.0.0/16 # RFC 3927 link-local (directly plugged) machines
acl localnet src 172.16.0.0/12 # RFC 1918 local private network (LAN)
acl localnet src 192.168.0.0/16 # RFC 1918 local private network (LAN)
acl localnet src fc00::/7 # RFC 4193 local private network range
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines
acl SSL_ports port 443
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 # https
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost manager
http_access deny manager
include /etc/squid/conf.d/*
http_access allow localhost
http_access deny all
coredump_dir /var/spool/squid
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320
新增配置
其中有include /etc/squid/conf.d/*
所以新增配置可在该文件夹添加新文件。如/etc/squid/conf.d/xda.conf
# 限制同一IP客户端的最大连接数
acl OverConnLimit maxconn 100
http_access deny OverConnLimit
# Safe_ports:允许安全更新的端口
# 邮箱服务
acl xSafe_ports port 993
acl xSafe_ports port 465
acl xSafe_ports port 143
acl xSafe_ports port 25
http_access deny !xSafe_ports
# 其他非标准 ssl
acl xSSL_ports port 3444
acl xSSL_ports port 63444
acl xSSL_ports port 4443
http_access deny CONNECT !xSSL_ports
visible_hostname xxx.xxx
cache_mgr xxx@xxx.com
# 以下是高匿的设置
request_header_access Via deny all
request_header_access X-Forwarded-For deny all
request_header_access From deny all
request_header_access Referer deny all
request_header_access User-Agent deny all
