我已经在DigitalOCean上安装了VPS并安装了squid3。 这里是/etc/squid3/squid.conf文件的尾部：
acl myhost src 1.2.3.4 # 1.2.3.4 is replaced by my ip at whatismyipaddress.com http_access allow myhost via off forwarded_for off request_header_access Allow allow all request_header_access Authorization allow all request_header_access WWW-Authenticate allow all request_header_access Proxy-Authorization allow all request_header_access Proxy-Authenticate allow all request_header_access Cache-Control allow all request_header_access Content-Encoding allow all request_header_access Content-Length allow all request_header_access Content-Type allow all request_header_access Date allow all request_header_access Expires allow all request_header_access Host allow all request_header_access If-Modified-Since allow all request_header_access Last-Modified allow all request_header_access Location allow all request_header_access Pragma allow all request_header_access Accept allow all request_header_access Accept-Charset allow all request_header_access Accept-Encoding allow all request_header_access Accept-Language allow all request_header_access Content-Language allow all request_header_access Mime-Version allow all request_header_access Retry-After allow all request_header_access Title allow all request_header_access Connection allow all request_header_access Proxy-Connection allow all request_header_access User-Agent allow all request_header_access Cookie allow all request_header_access All deny all 但是，不pipe我尝试什么，我一直在获取访问被拒绝的错误。
错误无法检索请求的URL
尝试检索url时遇到以下错误： http : //www.google.com/search ？
- 鱿鱼只加载半页
- 使用Nginx作为代理运行Apache的Owncloud
- Smoothwall Web代理VM阻止来自CDN的CSS文件
- DNAT通过代理连接到互联网的子网
- Apache ProxyPass：将请求的URL作为GETparameter passing给目标URL
