TcpIP connection to remote server not closing after each call.

Question

using urlconnection to connect to a remote server does not close tcp connection after use. Any ideas on how to force this closed.
This inturn causes subsequent calls to the remoteserver to use the existing tcp connections, slowing down the over <br>all connections because the remote server is not able to handle multiple requests using the same connection.
We are using a unix box running solaris 8.0 I believe and the <br>connection to the remote server is done over a dedicated line.
Here is what the code looks like. I believe I am doing all that I can to force the stream objects closed so that there is no lingering connections. Is there anything that I can do from a code perspective to assure that after each transaction all stream objects are dropped and closed so that the tcp connections close. Also, could there be other reasons why these connections stay open.
pls help.
try {
// Read the Login URL net connection output
URLConnection conn = new URL( url ).openConnection();
boolean inputOK = true;
if ( testInput ) {
     InputStream inConn = conn.getInputStream();
     InputStreamReader inStream = new InputStreamReader( inConn );
// read input stream for OK/FAILED
BufferedReader in = new BufferedReader( inStream );
String str = null;
Debug.println( this, "Response read" );
while ( ( str = in.readLine() ) != null ) {
System.err.println( str );
if ( ( str.indexOf( SUCCESS ) >= 0 ) || ( str.indexOf( LC_SUCCESS ) >= 0 ) ) {
Debug.println( this, "Found success " + str );
inputOK = true;
break;
else if ( ( str.indexOf( FAILURE ) >= 0 ) || ( str.indexOf( LC_FAILURE ) >= 0 ) ) {
Debug.println( this, "Found failure " + str );
inputOK = false;
break;
in.close();
     inStream.close();
     inConn.close();
     in = null;
     inStream = null;
     inConn = null;
Debug.println( this, "End of Response read" );
}

This is an issue with the browser rather than Java.
You are getting the same response, because the browser checks it's cache first and keeps serving up the same info from the cache.
Add a parameter to the URL so that the browser thinks you are submitting a form. Use the new methods in the URLConnection class, or you can manually add a GET parameter to the URL.
