Sebb commented on NET-538:
--------------------------

I've just checked, and none of the other classes (apart from 
DefaultSocketFactory of course!) instantiate Sockets directly - they all use 
the socket factory.

So it makes sense to do the same here, thus allowing the user to use their own 
socket factory if required.

> FTPHTTPClient should use socket factory to create sockets

>             Project: Commons Net
>          Issue Type: Bug
>          Components: FTP
>    Affects Versions: 3.3
>         Environment: win7 + java 64, apache-commons-net3.3.jar
>            Reporter: Dzmitry
>            Priority: Minor

> FTPHTTPClient can't set socket timeout when connecting to remote http proxy. 
> This may cause hangouts for calls to remote http ftp proxies.
> Expected: FTPHTTPClient  supports creation sockets with Factory methods. We 
> had same approach for regular FTPClient calling .setSocketFactory(...) method 
> and have control over socket creation.
> Actual: FTPHTTPClient  creates Socket inside public void connect(...) 
> directly, and it is impossible to set timouts since this object will be used 
> immediately. It is even impossible to inherit from FTPHTTPClient   to 
> override connect - since proxyHost, proxyPort and tunnelHandshake is private.
> so we may change 
>       _socket_ = new Socket(proxyHost, proxyPort);
> to 
>      _socket_ = _socketFactory_.createSocket();
> and add support for FTPHTTPClient  to handle socket factories for http 
> proxies calls.
> Is it possiible?
