Problem: Traffic sent to http://localhost or http://127.0.0.1 is not captured
Solution 1: Use Machine Name or Hostname
The simplest workaround is to use your machine name as the hostname instead of Localhost or 127.0.0.1. For example, rather than hitting:
http://localhost:8081/mytestpage.aspx
Instead visit:
http://machinename:8081/mytestpage.aspx.
