When calling an HTTP resource redirecting to a HTTPS one with a keepAlive agent. We get the following error:
```
TypeError [ERR_INVALID_PROTOCOL]: Protocol "https:" not supported. Expected "http:"

```
This can be tested here :
```
const http = require('http');
const https = require('https');
const axios = require('axios');
axios.get('http://www.photobox.fr', { httpAgent: http.Agent({ keepAlive:true }), httpsAgent: https.Agent({ keepAlive:true }) })
.then(response => {
console.log(response);
console.log(response.headers);
})
.catch(error => {
console.log(error);
});
```
Axios delegate the redirection to the follow-redirect package which accept an option `agents` for both http and https agent see : https://github.com/follow-redirects/follow-redirects#per-request-options
