Communication between Managed servlet using ProxyServlet

Question

          Hi,
          I have multiple Managed servers running on the same host, each hosting one web
          app on a particular port.
          The Admin server runs on port 7001.
          Example :
          The Managed Server hosting the Session Manager is running on 7100, and the
          Managed server hosting the DSLTools is running on port 7200.
          The following link works -
          http://localhost:7100/sessionmgr/servlet/sessionmgr
          Now when I click on DSLTools button on the page displayed by the above link,
          it takes me to
          http://localhost:7100/dsltools/servlet/dsltools
          whereas, I want it to take me to
          http://localhost:7200/dsltools/servlet/dsltools
          If I type the http://localhost:7200/dsltools/servlet/dsltools
          in the web browser, it works.
          So, ques is how can I go from Session Manager running on port 7100 to
          DSL Tools running on port 7200 ?
          I am trying Proxy by path using HttpProxyServlet, but it doesn't seem to work.
          I may be doing something wrong setting up HttpProxyServlet to handle this,
          but not sure what ? Any suggestions.
          I don't want to hard code the port numbers in the Session Manager servlet
          for obvious reasons.
          A quick response will be appreciated.
          Thank you very much

Hi jDee
I�m not sure that the connection is kept opened, I mean by �you need to know that http connexion, DataInputStreamand DataOutputStream are always opened� that I don�t make an explicit call to close() method.
My aim is to keep the http connection alive, because the Servlet needs to send with push mode some request to the Midlet. The Midlet handles the request and answers the Servlet.
the behavior of my application is the following:
DataInputStream dis=null;
DataOutputStream dos=null;
they are 3 modules: mobile client (J2ME), Mobile Server (J2ME), Coordinator (Servlet)
1-Server: open Httpconnection with Servlet
2-Server: open dis and dos
3-Server: send user & passwd trougth dos
4-Coordinator: check user&passwd
5-Coordinator: send response
6-Server:keep connection opened
7-Server: execut while(dis.avalaible()<1) {};
8-Client: send Request to coordinator
9-Coordinator: redirect Request to the right Server
10-Server: get request dis.read()
11-Server: handles the request
12-Server: answer the coordinator dos.write()
13-Coordinator:redirect the Response to the right Client
14-Client:get answer coming from Coordinator
