HTTP Connection issue in N8

Question

Hello Friends,
I have create J2ME application using LWUIT.
I am facing internet issue in that device.
Scenario :
Launch the application -> request to server using HTTP, working fine.
Minimize application, change mobile profile from GENERAL to OFFLINE mode.
keep in offline mode for 2 min.
Again change from OFFLINE to GENERAL mode.
open the minimize application.
again try to do same http request.
Now here I am facing issue, in http response, I am getting as :
"Invalid http response, http version mismath."
This issue is coming on only Nokia N8, I have tested on other device also and it is not giving same issue.
My code is like:
 [code]
public static synchronized String sendRequest(String url, String request, Vexx vexx) throws IOException {
HttpConnection connection = null;
InputStream in = null;
OutputStream out = null;
String response = "";
long len;
try {
connection = (HttpConnection) Connector.open(url, Connector.READ_WRITE);
connection.setRequestProperty("User-Agent", System.getProperty("microedition.platform"));
connection.setRequestProperty("HTTP-Version", "HTTP/1.1");
connection.setRequestMethod(HttpConnection.POST);
connection.setRequestProperty("Content-Type", "application/vnd.syncml+xml");
connection.setRequestProperty("Content-Language", "en-US"); connection.setRequestProperty("Content-Length",String.valueOf(request.length()));
out = connection.openOutputStream();
out.write(request.getBytes());
out.close();
in = connection.openInputStream();
len = connection.getLength();
if (len < 0) {
ByteArrayOutputStream bytestream = new ByteArrayOutputStream();
int ch;
while ((ch = in.read()) != -1) {
bytestream.write(ch);
response = new String(bytestream.toByteArray());
bytestream.close();
} else {
DataInputStream data_in = new DataInputStream(in);
byte[] response_data = new byte[(int) len];
data_in.readFully(response_data);
data_in.close();
in.close();
data_in = null;
AppConstants.LOG +="11";
response = new String(response_data);
AppConstants.LOG +="response: " + response;
} catch (Exception ex) {
AppConstants.LOG += "EXC = " + ex.getMessage();
} finally {
try {
in = null;
out = null;
if (connection != null) {
connection.close();
connection = null;
} catch (Exception e) {
return response;
 [code]
In above code, when it connects first time, there is no issue, but on second time, it give error on line: in = connection.openInputStream();
I have create one new application for testing purpose as well, using J2ME API, in that I have just call connection class as same above on command, and try same scenario:
install -> test -> working fine.
change profile from general to offline and again offline to general -> and test again.
Working fine.
After that I have also use LWUIT4IO package for connection in LWUIT application.
In that also I am facing same issue. "Invalid http version...."
Please help me to solve ASAP.

you can re-open the connection after reading a response - here is one way to do a self-replicating request -
function newRequest(): HttpRequest {
    return HttpRequest {
        location: "http:...";
        onInput: function(is: java.io.InputStream) {
            try {
                // ... read response from input stream and then spawn a new request
                newRequest().enqueue();
            } finally {
                is.close();
newRequest().enqueue();
