url parameters in asp.net webtier app

  The RBServer\Demos\WebTier\CustomParameters demo shows how to do this. (You
  need also run the RBServer\Demos\Server\CustomParameters server app).
  
  Here is a brief overview:
  
  1. Create a TrsWebRequest object. Pass the url parameters to the
  constructor.
  
  var
  lWebRequest: TrsWebRequest;
  begin
  
  {use the incoming request parameters to create a TrsWebRequest}
  lWebRequest := rsWebTier1.CreateWebRequest(Request.QueryFields,
  Request.Content);
  
  end;
  
  2. See the online help topic for TrsWebRequest. Note that its
  ContentParameters[] array property contains the url params received from the
  web browser (i.e. the ones you passed in the constructor).
  
  In your custom webtier logic you can read these parameters and use them to
  populate the WebRequest SessionParameters[], ServiceParameters[], and
  AutoSearchParameters[] arrays - which will be sent to the report server. The
  ServiceParameters[] array property can be used for custom report parameters.
  The SessionParameters[] array property can be used for custom session
  parameters. There is also an AutoSearchParameters property.
  
  3. The WebTier.ProcessWebRequest method is overloaded. You can pass it the
  WebRequest object
  
  myWebTier.ProcessWebRequest(myWebRequest);

  Hi Nard,
  
  thanx for the quick response: My problem is how to fit it in the
  webtiercomserver.
  It has a datamodule. The demo RBServer\Demos\Server\CustomParameters has
  a webmodule.
  So in webtiercomserver there is no action editor and i have no params like
  Request.QueryFields and Request.Content.

  For the WebTierComServer example, the TRBWebTier.ProcessWebRequest method is
  being called rather than a web module action. The QueryString and
  ContentString parameters are parsed into a Parameter list. You can pass this
  list to the constructor of a WebRequest object.
  
  function TRBWebTier.ProcessWebRequest(const QueryString,
  ContentString: WideString): WideString;
  begin
  
  lParameters := TStringList.Create;
  
  lsQueryString := QueryString;
  lsContentString := ContentString;
  
  TrsWebRequestParser.ParseContent(lsQueryString, lParameters);
  TrsWebRequestParser.ParseContent(lsContentString, lParameters);
  
  {******use the incoming request parameters to create a TrsWebRequest}
  lWebRequest := rsWebTier1.CreateWebRequest(lParameters, nil);
  
  {*****add logic here to read the webrequest.ContentParameters and populate
  the webrequest SessionParameters and ServiceParameters }
  
  
  lsResponse := uWebTierModule.WebTier.ProcessWebRequest(lWebRequest);
  
  lwResponse := lsResponse;
  
  Result := lwResponse;
  
  finally
  lParameters.Free;
  end;
  
  
  
  end;

  Nard,
  
  Thanx for your explanations,
  i was totaly on the wrong track (read lost) working too complicated.
  I added your code line:
  lWebRequest := rsWebTier1.CreateWebRequest(lParameters, nil);
  then added the parameter using
  lWebRequest.SessionParameters.Add('onderdeel',value);
  and that was all i needed.
  
  thanx again for your input efforts
