Accept

通过header  HTTP_X_FORWARDED_FOR 可以知道代理服务器的服务器名以及端口,
通过HTTP_VIA可以知道客户的内部ip,这会带来一些安全问题,并且某些论坛会发现用的是代理访问,怎么让squid隐藏这些信息呢.
通过研究squid的源代码,发现在etcsquidsquid.conf中添加2行
       header_access Via deny all
       header_access X-Forwarded-For deny all
就可以把它关闭

要去掉其他的header,也可以照此操作

//下面是我写的一个透过代理取IP的函数。  
  public   static   string   getUserIP()  
  {  
  if(HttpContext.Current.Request.ServerVariables["HTTP_VIA"]!=null)  
  {      
  return   HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();      
  }  
  else  
  {      
  return   HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"].ToString();      
  }      
  }

 

 

附上几个常用Request.ServerVariables：

本文件ip路径：<%="http://" & request.servervariables("SERVER_NAME")& request.servervariables("SCRIPT_NAME") %> <br/>
本机ip:<%=request.servervariables("REMOTE_ADDR")%> <br/>
服务器名:<%=Request.ServerVariables("SERVER_NAME")%><br/>
服务器IP:<%=Request.ServerVariables("LOCAL_ADDR")%><br/>
服务器端口:<%=Request.ServerVariables("SERVER_PORT")%><br/>
服务器时间:<%=now%><br/>
IIS版本:<%=Request.ServerVariables("SERVER_SOFTWARE")%><br/>
脚本超时时间:<%=Server.ScriptTimeout%><br/>
本文件路径:<%=server.mappath(Request.ServerVariables("SCRIPT_NAME"))%><br/>
服务器CPU数量:<%=Request.ServerVariables("NUMBER_OF_PROCESSORS")%><br/>
服务器解译引擎:<%=ScriptEngine & "/"& ScriptEngineMajorVersion &"."&ScriptEngineMinorVersion&"."& ScriptEngineBuildVersion %><br/>
服务器操作系统:<%=Request.ServerVariables("OS")%> <br/>
支持的文件类型：<%=Request.ServerVariables("HTTP_ACCEPTccept")%> <br/>
访问的文件路径：<%=Request.ServerVariables("HTTP_URL")%> <br/>
用户代理的信息：<%=Request.ServerVariables("HTTP_USER_AGENT")%> <br/>
