通用FUNCTION,如果不能取真实IP,就会取代理IP

Private 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
