Use BigIP to realize one to many TCP mapping

Thanks!

I have followed your suggestion and it seems that at the second time, the HTTP_REQUEST event also not be triggered.

Here is our iRules:

when HTTP_REQUEST
{
    set uri [HTTP::uri]
    log "uri $uri"
    set uritype [findstr $uri "cs?version" 0 "&"]
    if { $uritype ne "" }
    {
       log "9000"
       set realclient [HTTP::header "x-nokia-ipaddress"]
       log "x-nokia-ipaddress: $realclient"
       set key [list $realclient any]
       set peerip [session lookup uie $key]
       if {  $peerip equals "" }
       {
          log " key not exist"
          LB::detach 
          snat $realclient  
          pool CS_NIN_HTTP_Pool
       }
       else {
          log " key exist" 
          log "x-nokia-ipaddress $realclient"
          snat $realclient
          node $peerip "9000"
       }
    }
    else
    {
       log "8080"
       pool NIN_Web_Proxy_Pool 
    }
}
when HTTP_RESPONSE {
    set serverport [TCP::remote_port]
    log "serverport : $serverport"
    if { $serverport equals "9000" }
    {
        log "server: [IP::remote_addr]"
        set key [IP::local_addr]
        set key2 [list $key any]
        set oldvalue  [session lookup uie $key2]
        log "respond :[HTTP::payload]"
        log "oldvalue: $oldvalue"
        if { $oldvalue equals ""}
        {
           set value [IP::remote_addr]
           log "in session add before $key2 ->$value"
           session add uie $key2  $value 120
           log "in session after add"
        }
        log "http release"
        HTTP::release
        TCP::close
        HTTP::collect
        LB::detach
        TCP::collect 
     }     
}

And I use a simple java client, here it is:

import java.io.*;
import java.net.*;
import java.util.*;
public class client_start3{
       public static void main(String []args){
     try{
byte[] b = new byte[4]; 
 b[0] = new Integer(10).byteValue(); 
 b[1] = new Integer(128).byteValue(); 
 b[2] = new Integer(16).byteValue(); 
 b[3] = new Integer(51).byteValue(); 
        InetAddress addr1 =   InetAddress.getByAddress(b);
Socket socket = new Socket(addr1,80);
BufferedReader in = new BufferedReader(
  new InputStreamReader(socket.getInputStream()));
PrintWriter out = new PrintWriter(new   BufferedWriter(
new OutputStreamWriter(socket.getOutputStream())),
true);
out.println("GET /cs?version=1.0&cmd=start HTTP/1.1\r\nUser-Agent: UNTRUSTED/1.0\r\nContent-Length: 0\r\nx-nokia-ipaddress:10.128.16.44\r\nHost:10.128.16.51:80\r\n");
while(true){
     String str = in.readLine();
     System.out.println(str);
     if(str==null)
break;
}
                out.flush();
try{
    Thread.currentThread().sleep(5000);
}catch(Exception e){}
out.println("GET /cs?version=1.0&cmd=start HTTP/1.1\r\nUser-Agent: UNTRUSTED/1.0\r\nContent-Length: 0\r\nx-nokia-ipaddress:10.128.16.105\r\nHost:10.128.16.51:80\r\n");
while(true){
     String str = in.readLine();
                     if(str==null)
break;
     System.out.println(str);
}
while(true){}
   }
   catch(Exception e){
System.out.println(e.toString());
   }
}
}

This is the log when I use java client to test this iRules.

Could you give me some suggestion? Thanks very much!
