const axios = require('axios');

axios.get('http://127.0.0.1:10081/',{ headers: { 'AuThorization': 'Rear Test', 'ProXy-AuthoriZation': 'Rear Test', 'coOkie': 't=1' } }).then(function (response) { console.log(response); }) When I meet the cross-domain redirect, the sensitive headers like authorization and cookie are cleared, but proxy-authentication header is kept.
