如何通过配置F5 使业务程序获得真实客户端IP 及 IIS 日志记录真实客户端的IP

如何通过配置F5   使业务程序获得真实客户端IP   及 IIS 日志记录真实客户端的IP
一:变更F5配置

1:Local Traffic－Profiles－Http－改“Insert XForwarded For”为Enable
2:Local Traffic－Virtual servers－点击需要改动的VS－将Type选项更改为Standard－将HTTP Profile 选项更改为Http

 

 

二:配置IIS 使IIS日志记录真实客户端的IP

1:注意附件中的 F5XForwardedFor.dll
2:IIS站点--属性--ISAPI筛选器--添加 F5XForwardedFor.dll

 

三:编写业务程序获得真实客户端IP  代码如下：(代码示例 使用VB.Net)

        Dim strHTTPXForwarded As String = ""
        Try
            If Request.ServerVariables.Get("HTTP_X_FORWARDED_FOR") Is Nothing Then
                strHTTPXForwarded = Request.UserHostAddress()
            Else
                strHTTPXForwarded = Request.ServerVariables.Get("HTTP_X_FORWARDED_FOR").ToString()
            End If
        Catch ex As Exception
            'strHTTPXForwarded = Request.UserHostAddress()
        End Try
