title: JMeter Recording: 401 Unauthorized response after changed HTTP proxy to localhost
body: <p>I just start learning JMeter. I'm trying to use JMeter to record my company websites, .NET web application.</p>
  
  <p><strong>My issue is that</strong>: <strong>For security, to access the websites, we have to config "Manual proxy configuration" to 10.x.x.x:3128. However, to record in JMeter I have to change the config to localhost, port 3128.</strong> </p>
  
  <p>After I changed the config to localhost, I click Start button of HTTP Test Script Recorder then I click on any link, the Authorization dialog displays and I keep getting 401 unauthorized error although I enter correct username/password. </p>
  
  <p>I tried to use HTTP Authorization Manager, HTTP Request Defaults or HTTP Request but they do not work. </p>
  
  <p>Could anyone help me out? </p>
