客户端IP有两种情况，一个是代理服务器上网的，另一种是直接上网的，所以要获取客户端IP也需要分开来获取。<%Function getIP() Dim strIPAddr If Request.ServerVariables("HTTP_X_FORWARDED_FOR") = "" OR InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), "unknown") >0 Then  strIPAddr = Request.ServerVariables("REMOTE_ADDR") ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",") > 0 Then strIPAddr = Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), 1, InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",")-1) ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";") > 0 Then strIPAddr = Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), 1, InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";")-1) Else  strIPAddr = Request.ServerVariables("HTTP_X_FORWARDED_FOR") End If getIP = Trim(Mid(strIPAddr, 1, 30)) End Function %>
