我在配置页面时遇到问题，该页面通过Squid上的Ubuntu 16.04重定向首次访问。以下是/etc/squid/squid.conf下的相关配置。我试图按照文档和网络中的示例进行操作。
external_acl_type splash_page %SRC /usr/lib/squid/ext_session_acl -b /var/lib/squid/session.db
acl existing_users external splash_page
deny_info 511:/etc/squid/splash.html existing_users
http_access deny !existing_users
Squid启动，然后以下列
# service squid status

文件存在并且（我认为）配置了良好的权利：
# ll /usr/lib/squid/ext_session_acl
-rwxr-xr-x 1 root root 10208 juil. 26 15:11 /usr/lib/squid/ext_session_acl*
# ll /etc/squid/splash.html
-r--r--r-- 1 root root 11 oct. 29 11:18 /etc/squid/splash.html
# ll /var/lib/squid/session.db
-rw-r----- 1 proxy root 1 oct. 29 13:43 /var/lib/squid/session.db
我错过了什么？这是我第一次使用squid所以我希望我不会问一个愚蠢的问题。
