squid做反向代理時，要注意的安全設置
使用squid的網站
#curl -I www.php-oa.com
HTTP/1.0 200 OK
Date: Tue, 15 Jan 2008 03:45:29 GMT
Server: Apache
X-Pingback: https://www.php-oa.com/xmlrpc.php
Content-Type: text/html; charset=UTF-8
X-Cache: MISS from cnc.onezone.com
X-Cache-Lookup: MISS from cnc.onezone.com:80
Via: 1.0 cnc.onezone.com:80 (squid/2.6.STABLE6)
Connection: close
正常的沒有使用squid的。
#curl -I www.php-oa.com
HTTP/1.1 301 Moved Permanently
Date: Tue, 15 Jan 2008 03:49:30 GMT
Server: Apache
X-Pingback: https://www.php-oa.com/xmlrpc.php
Location: https://www.php-oa.com/
Connection: close
Content-Type: text/html; charset=UTF-8
發現不一樣了沒，人家查到你的server使用的是什麼，然後還有你使用的是不是squid，還是真實的服務器.
在你的squid.conf中加入
header_access Via deny all
header_access Server deny all
header_access X-Cache deny all
header_access X-Cache-Lookup deny all
#不顯示版本信息
httpd_suppress_version_string off
就可以把它關閉
要去掉其他的header,也可以照此操作，下麵是列表。
