环境：Freebsd4.8+apache1.3.28

CODE:
ProxyRequests On
CacheRoot /mnt/cache CacheSize 5000 CacheGcInterval 4 CacheMaxExpire 24 CacheLastModifiedFactor 0.1 CacheDefaultExpire 1 按照常规，第一次浏览，IE正常下载数据，然后按F5刷新页面，应该先检查本地缓存，如果本地有缓存，而没有过期的话，就返回304，直接显示缓存中的数据，而不会再从服务器下载一次了 但是我这得情况是，我访问一次后，按F5刷新页面，IE还是去服务器下载数据，本地没有缓存 而我访问，比如百度首页，就能会缓存，而不再从服务器下载数据了，这说明我本地的浏览器没问题。 我抓了一下访问的http头，大家看一下 第一次访问我的页面
