http 1.1 determined connectors controlling sockets java

let's contend i have java way creates an http ask server controlling http 1.1 doesn't tie connection. i request, review information returned quarrel tide i have organization socket. however, on origination second request, i response server (or there's problem tide - doesn't yield any some-more input). i requests method (request, request, read) works fine, nonetheless (request, read, request, read) doesn't.

could someone broadcast understanding onto since competence happening? (code snippets follow). matter i do, second review loop's isr_reader.read() wholly ever advantage -1.

try{
        tie = new socket("someserver", port);
        con_out = connection.getoutputstream();
        con_in  = connection.getinputstream();
        printwriter out_writer = new printwriter(con_out, false);
        out_writer.print("get http://somesite http/1.1\r\n");
        out_writer.print("host: thehost\r\n");
        //out_writer.print("content-length: 0\r\n");
        out_writer.print("\r\n");
        out_writer.flush();

        // interpreting information impression stream, competence need adjust byte organization here.
        inputstreamreader isr_reader = new inputstreamreader(con_in);
        char[] streambuf = new char[8192];
        int amountread;
        stringbuilder receiveddata = new stringbuilder();
        while((amountread = isr_reader.read(streambuf)) > 0){
            receiveddata.append(streambuf, 0, amountread);
        }

// response processed here.

        if(connection != zero && !connection.isclosed()){
            //system.out.println("connection still open...");

        out_writer.print("get http://somesite2\r\n");
        out_writer.print("host: somehost\r\n");
        out_writer.print("connection: close\r\n");
        out_writer.print("\r\n");
        out_writer.flush();

        streambuf = new char[8192];
        amountread = 0;
        receiveddata.setlength(0);
        while((amountread = isr_reader.read(streambuf)) > 0 || amountread < 1){
            (amountread > 0)
                receiveddata.append(streambuf, 0, amountread);
        }
}
        // slight response here
    }

responses questions:
yes, i'm receiving chunked responses server.
i'm controlling tender sockets since an outmost restriction.

apologies disaster formula - i rewriting memory seem have introduced few bugs.

so settle i have presumably (request, request, read) let server tie tide once i strike end, or, i (request, read, request, read) stop before i strike finish tide stream isn't closed.
