How to implement SuperSocket - sockets

Question

I am trying to implement Supersockets - https://supersocket.codeplex.com/ for a project i am working on. I have the a server that uses configuration to run.
In my project
I have referenced:
SuperSocket.Common,
SuperSocket.SocketBase,
SuperSocket.SocketEngine
I added the following config section:
<configSections>
<section name="superSocket" type="SuperSocket.SocketEngine.Configuration.SocketServiceConfig, SuperSocket.SocketEngine" />
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<appSettings>
<add key="ServiceName" value="SomeService" />
</appSettings>
<superSocket logFactory="ConsoleLogFactory"
disablePerformanceDataCollector="true"
maxWorkingThreads="500"
maxCompletionPortThreads="500"
minWorkingThreads="5"
minCompletionPortThreads="5">
<servers>
<server name="SomeService"
serverType="SomeService.Server.SomeService, SomeService"
ip="192.168.1.107"
port="4096"
disableSessionSnapshot="true"
clearIdleSession="false"
maxConnectionNumber="10"
sendWelcome="false">
</server>
</servers>
<logFactories>
<add name="ConsoleLogFactory"
type="SuperSocket.SocketBase.Logging.ConsoleLogFactory, SuperSocket.SocketBase" />
</logFactories>
</superSocket>
I also created the server and session class as follows:
namespace SomeService.Server
{
class SomeService: AppServer<SomeServiceSession>
{
protected override bool Setup(IRootConfig rootConfig, IServerConfig config)
{
return base.Setup(rootConfig, config);
}
protected override void OnStartup()
{
base.OnStarted();
}
protected override void OnStopped()
{
base.OnStopped();
}
}
}
namespace SomeService.Server
{
class SomeServiceSession : AppSession<SomeServiceSession>
{
protected override void OnSessionStarted()
{
// this.Send("Welcome to SuperSocket Telnet Server");
}
protected override void HandleUnknownRequest(StringRequestInfo requestInfo)
{
this.Send("Unknow request");
}
protected override void HandleException(Exception e)
{
this.Send("Application error: {0}", e.Message);
}
protected override void OnSessionClosed(CloseReason reason)
{
//add you logics which will be executed after the session is closed
base.OnSessionClosed(reason);
}
}
}
At this point the Server runs and it listens on a port as intended. Here is a wireshark representation of what i would want to do With SuperSocket http://imgur.com/rxKJbOD.
If you see on the request reply one chuck of the data :
.MSH|^~\&|MRI|ABC|||201403251406||QRY|173883426|P|2.1
QRD|201403251406|R|I|xxxxx|||25^RD|AB851656^|MPI
QRF|UPI||||
.
is from the client and
.MSH|^~\&|MRI|ABC|||201403251406||QRY|173883426|P|2.1
QRD|201403251406|R|I|xxxx|||25^RD|AB851656^|MPI
QRF|UPI||||
MSA|AA|173883426
.
is from the server. the response returned varies depending on the request and what is created after the business logic executes (but it is always going to be the same format- HL7 en(dot)wikipedia(dot)org/wiki/Health_Level_7 ). HL7 follows MLLP messaging format where each message begins with a Start Block code (0x0B) and each segment within the message is terminated with a Carriage Return code (0x0D) and each message is terminated by an End Block code (0x1C) followed by a Carriage Return code (0x0D). Once i get the request i have a business logic class that parses out the values, calls a web service gets the data and constructs a the tcp reply. What i would like to know is where in SuperSocket can i have a method or event listener to read the buffer and do my business logic and return the response for the same session. I know that there are concepts like filters and commands in SuperSocket but i haven't been able to figure them out. Any help is greatly appreciated. Let me know if you need additional detail.
