Monitor traffic to localhost from IE or .NET

To monitor traffic sent to http://localhost or http://127.0.0.1 from IE8 or below or the .NET Framework:

• Use your machine name as the hostname instead of Localhost or 127.0.0.1
  For example, instead of
  

  http://localhost:8081/mytestpage.aspx

  Go to:

  http://machinename:8081/mytestpage.aspx

  Use one of these addresses:
  -To use the IPv4 adapter (recommended for the Visual Studio test webserver, codename: Cassini):

  http://ipv4.fiddler

  -To use the IPv6 adapter:

  http://ipv6.fiddler

  -To use localhost in the Host header:

  http://localhost.fiddler

  Click Rules > Customize Rules… and add this code to the Rules file:

  static function OnBeforeRequest(oSession:Fiddler.Session){
  if (oSession.HostnameIs("MYAPP")) { oSession.host = "127.0.0.1:8081"; }
  }

  Now, http://myapp will act as an alias for 127.0.0.1:8081

  监视从IE或者.NET到本地主机的流量

  要监视从IE8或更低版本或.NET Framework发送到http:// localhost或http://127.0.0.1的流量，请执行以下操作：

• 使用您的计算机名作为主机名，而不是Localhost或127.0.0.1

• 例如，不要使用

  http://localhost:8081/mytestpage.aspx

  转到:

  http://machinename:8081/mytestpage.aspx

  使用其中一个地址:
  -使用IPv4适配器(建议用于Visual Studio测试webserver，代号:Cassini):

  http://ipv4.fiddler

  使用IPv6适配器:

  http://ipv6.fiddler

  要在Host标头中使用localhost：

  http://localhost.fiddler

  单击 Rules > Customize Rules… 然后添加规则到文件里面

  static function OnBeforeRequest(oSession:Fiddler.Session){
  if (oSession.HostnameIs("MYAPP")) { oSession.host = "127.0.0.1:8081"; }
  }

  现在, http://myapp 将作为一个别名 127.0.0.1:8081
