ProxySelector changes URL's scheme from https:// to socket://

Question

I need to access Facebook but all outgoing communication is blocked on our server so I have to use proxy.

I initialize proxies with:

ProxySelector.se         


        

Answer 1

It's not the ProxySelector that changes the scheme, but the SocketFactory opening a Socket. If the SocketFactory is null a SOCKS socket will be created by default which only allows SOCKS proxies. I don't know anything about Sockets and cannot tell you if there's a way to make it work with HTTP proxies.

But using another approach may help, since Apache HttpClient seems to have its own way to configure proxies.

client.getHostConfiguration().setProxy(proxyHost, proxyPort);

if (proxyUser != null) {
    client.getState().setProxyCredentials(new AuthScope(proxyHost, proxyPort), 
        new UsernamePasswordCredentials(proxyUser, proxyPassword));
}
