Proxy-Not able to read from socket for browser IE only for authorized sites

Question

Hi,
I have implemented proxy server using socket connection. For Mozila it works properly, but not for IE.
First it asks for proxy authentication, after providing the username and password for proxy in mozila its asks authentication for the authorized sites and its working properly. But in IE it just ask for proxy authorization and gives error as "you are not authorised to view this page" internally when I went through the code only first time its able to read the request and gives the response, but for the authorized site it wont ask for the username and password. After some time it throws the "Socket connection: reset" exception.
Creates the connection:-
               while(running){
                    try{
                         clientSocket = serverSocket.accept();
                                }catch(SocketException se){
                                        se.printStackTrace();
                               try{     
                         new HttpClientConnectionHandler(sockCon);
                    } catch(IOException se) {
                                         se.printStackTrace();
                               }Sends requests and gets the response:-
boolean continueSession = true;
          try{
            SCConnectionManager.increementConnCount();
          while (continueSession){
                    continueSession=false;
                HttpHeader request = rqHandler.getRequest();
                    String con = request.getHeaderValue ("Connection");
               boolean clientPersistentConnection = false;
                    String pcon = request.getHeaderValue ("Proxy-Connection");
                    System.out.println("request = "+request.toString());
                    if( ( request.getHTTPVersion().equalsIgnoreCase("HTTP/1.1")
                                        && !( pcon.equalsIgnoreCase("close") ) )
                              || ( request.getHTTPVersion().equalsIgnoreCase("HTTP/1.0")
                                && ( pcon.equalsIgnoreCase("Keep-Alive") ) ) ){
                              //tempComment     debug("CLIENT Keeping connection true !!!!!! ");
                         clientPersistentConnection = true;
                resHandler.Handle(request);     // Returns boolean ...can check its value...
                         if ( clientPersistentConnection == true && resHandler.connectionPersistent == true ) {
                                   //tempComment    
                              debug("SERVER Keeping connection true !!!!!! ");
                              continueSession=true;
                              if ( resHandler.surfAsServer == true ) {
                                   client.setTimeout( persistentConnectionClientReadTimeout );
                         debug("CONTINUING CLIENT CONNECTION "+continueSession);
               System.out.println("out of while loop continue sess = "+continueSession);
          }catch(IOException ioe){
               log(ioe);     
               if(qlc.qsm.log.Logger.debugOut) {
                    ioe.printStackTrace();
          } finally {
               synchronized( this ) {
                    int connCount = SCConnectionManager.decreementConnCount();
                SCConnectionManager.updateLastRequestTime();
               close();
     }It does not come out of above while loop.

Sorry, while copy the code one line was missing.
code is:-
while(running){
                    try{
                         clientSocket = serverSocket.accept();
                          } catch (SocketException se) {
                          se.printStackTrace();
                         continue;
                    }catch(IOException se){
                                   continue;
                    try{
                                   SocketConnection sockCon=new SocketConnection(clientSocket);
                                    new HttpClientConnectionHandler(sockCon);
                               } catch(IOException se) {                         
                         se.printStackTrace();
                                         if ( clientSocket != null ) {
                              try {
                                   clientSocket.close();
                              } catch ( Exception exc ){
                                   clientSocket = null;
                              decrementHttpCount();
                              }
