instream.read() ---- In SSL mode

[Guru Prasad P.S]

While reading content ( attachment in response ) from the input stream in SSL 
mode throws java.net.SocketException: Socket Closed

Note: This Exception is thrown only when response has an attachment.

In non ssl mode there is no issue.
    InputStream instream = entity.getContent();
    int l;
    byte[] tmp = new byte[2048];
    while ((l = instream.read(tmp)) != -1) {
    }

Making use of BufferedHttpEntity solves this issue. (Is it a right approach?)
entity = new BufferedHttpEntity(entity)
entity.getContent();


Use of BufferedHttpEntity() has any performance impact?
