I'd like to get a suggestion how to configure to AhcWSClient in Akka-http 10.10 to AcceptAnyCertificate. It seems either akka-http ignores this setting or overwrites it somewhere. Here it is the config:

```
val config = new AhcWSClientConfig()
config.wsClientConfig.ssl.loose.withDisableHostnameVerification(true)
config.wsClientConfig.ssl.loose.withAllowUnsafeRenegotiation(Some(true))
config.wsClientConfig.ssl.loose.withAllowWeakProtocols(true)
config.wsClientConfig.ssl.loose.withAllowWeakCiphers(true)
config.wsClientConfig.ssl.loose.withAcceptAnyCertificate(true)
config.wsClientConfig.ssl.withHostnameVerifierClass(classOf[AllowAllHostnameVerifier])

val sslpcfg = com.typesafe.sslconfig.ssl.SSLParametersConfig()
sslpcfg.withClientAuth(ClientAuth.None)
config.wsClientConfig.ssl.withSslParametersConfig(sslpcfg)
val httpClient = AhcWSClient(config)

```

And here is the response and error with wrong certificate:

```

It seems like an old bug to me which was raised in WSClient in 2016, 2013, etc. and then was fixed.
Also the suggestion is that `withAcceptAnyCertificate` is ignored completely as was suggested to remove in future versions of akka in about 2016.

The problem raises with this url connection
[https://www.html5rocks.com/ru/tutorials/internals/howbrowserswork/](https://www.html5rocks.com/ru/tutorials/internals/howbrowser/)

Same url is successfully connected to by AhcWSClient without `www` prefix

Any suggestion are appreciated
