上面是用webmin的官方squid模块生成的。设置下载文件大小限制是在Cache Options页面的
Maximum reply body sizes Size (kB) For requests matching ACLs (leave empty for all)
这项下面。这个可以限制网页上的视频，不用知道网址也能限制。
第1个框填文件大小数字(纯数字，不要加单位)。第二个框最前面要填文件大小的单位(例如MB),接着是acl选择项。
例如：
10 MB working_time_am general_client !working_website !unlimited_client
10 MB working_time_pm general_client !working_website !unlimited_client
上面两行用途是限制普通用户在工作时间访问超过10MB大小的非工作网站。这样超过10MB大小的网页视频就打不开了。
