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
I noticed the error object has a `toJSON` method but when I tried to use it in my typescript code it complained it didn't exist, even though I was using the `AxiosError` type.
* README.md COOKBOOK.md: minor fixes
* simplify language
* ECOSYSTEM: create a few categories
* Examples: log port listening to
* upgrade bootstrap 3 -> 4 in examples
bootstrap 4 is slightly smaller then 3.2.0
so it should also help load examples faster
* categorize 0.19 items a little differently
surface user/consumer changes first
Inside Axios.prototype.request function, It's forced to set
method to 'get' after `mergeConfig` if config.method exists, which makes the defaults.method not effective.
* Adding tests to show config.url mutation
Because config.url is modified while processing the request
when the baseURL is set,
it is impossible to perform a retry with the provided config object.
Ref #1628
* Fixing url combining without modifying config.url
As config.url is not modified anymore during the request processing.
The request can safely be retried after it failed with the provided
config.
