I created a standalone app using Delphi XE2 and Intraweb 12.2.37.  The app functions properly with one user but when a second user is active, keystrokes from user one are affecting user 2 and windows messages intended for user one are displayed to user 2. Server app show 2 sessions. What am I missing?

Is there a way to calculate the width of the browser so that I can set the left property of the iwlabel.
I'm trying to make sure the Label is in the horizontal center of the screen no mater what device is used?
 
Thanks

Hi!

IWIndyHTTPClient does not insert the CustomHeaders value into the request as of Intraweb 15.4.x.
(This worked fine in version 15.3.12.)

Example: the 'Signature' parameter was not included in the sent request (v.15.4.2):
xHTTP := TIWIndyHTTPClient.Create;
xHTTP.CustomHeaders.Add( 'Signature:abcdef123456' );
xHTTP.Post( address, req, contenttype);

But it works fine with this code:
xHTTP:=TidHTTP.Create(nil);
xHTTP.Request.ContentType:=contenttype;
xHTTP.Request.CustomHeaders.Add( 'Signature:abcdef123456' );
response:=iHTTP.Post( address, req );

Will there be a fix for TIWIndyHTTPClient?

Best regards:

Hi @all,

An IWSelect with SelectOption soServerSide works fine.

But how to set an initial/default item?

I tried with IWSelect.ItemIndex := IWSelect.Items.Add(AText) but without success.

Anyone has an solution for this?!

Thanks for hints in advance!

Seasonal greetings to y'all;
When I go to DOS prompt (a.k.a. Command Prompt) and run ping like this

Delphi says TWebRequestHandler.MaxConnection is 32, which means 32 requests can be handled concurrently (of course, more client sessions can exist, but only 32 of them can be concurrently active and being processed).

Does this also account for IntraWeb? The maxmum number of sessions is very high (thousands, at least), but can we "only" have 32 concurrent active sessions being processed in ISAPI DLLs?

Hello,
I'm facing a problem that appeared using 15.3.12 version and higher (I've just tried 15.4.1).
In 15.2.63 that we use in production it works good.
Also, the problem is only on ISAPI module, compiling SA executable it's ok.

In our IWForm we call the application itself to start a new session passing some parmeter that we use to automatically log in, but the content it's not important.

procedure TWMyForm.MyButtonAsyncClick(Sender: TObject; EventParams: TStringList);
...
begin
  S:='var formIris = document.forms["SubmitForm"]; ' +
    'formIris.setAttribute("action","' + GGetWebApplicationThreadVar.InternalUrlBase + '/start' + '"); ' +
    'document.getElementById("HIDDEN_xusr").value = "user"; ' +
    'document.getElementById("HIDDEN_profilo").value = "profile"; ' +
    'formIris.elements["IW_SessionID_"].value="";' +
    'formIris.elements["IW_TrackID_"].value="";' +
    'SubmitClick("' + btnConferma.HTMLName + '", "", true); ';
  GGetWebApplicationThreadVar.CallBackResponse.AddJavaScriptToExecuteAsCDATA(S);

//After several operation, a new session is going to start; the call stack show me this call:
TIWServerSession.GetStartParams (no source available, I wasn't able to debug)

//soon after in IWApplication:
class procedure TIWParamsString.EncodeParams(const AParamsList: TStrings);
var
  i: Integer;
begin
  for i := 0 to AParamsList.Count - 1 do begin
    AParamsList[i] := TURL.ParamsEncode(AParamsList[i]);
  end;
end;

we have:
- AParamsList.Text = 'azienda=AZIN'#$D#$A'BTNANNULLA='#$D#$A'BTNCHIUDI_WC012FVISUALIZZAFILEFM='#$D#$A'BTNCONFERMA='#$D#$A'BTNSENDFILE='#$D#$A'CMBPROFILONUOVO=0'#$D#$A'database=IRIS'#$D#$A'EDTAJAXFORMID=W020FCambioProfilo31591375'#$D#$A'EDTPROFILOATTUALE=D'#$D#$A'GRDMEMOAJAX='#$D#$A'IW_Action=BTNCONFERMA'#$D#$A'IW_ActionParam='#$D#$A'IW_FormClass=TW020FCambioProfilo'#$D#$A'IW_FormName=W020FCambioProfilo'#$D#$A'IW_height='#$D#$A'IW_Location_=http://localhost/Iris32/W000PIrisWEB_IIS.dll/nnIGyEVlGfm5HVTjRMrNnWpaoVS/'#$D#$A'IW_Offset=0,0'#$D#$A'IW_SessionID_='#$D#$A'IW_TrackID_='#$D#$A'IW_width='#$D#$A'IW_WindowID_=wid=FRG~vjMCuGjy6z5eTYWBoef9ggm'#$D#$A'loginesterno=S'#$D#$A'profilo=R'#$D#$A'pwd='#$D#$A'usr='#$D#$A'WR010SCROLLLEFT=0'#$D#$A'WR010SCROLLTOP=0'#$D#$A'xusr=AV2y3wiTbaBdaQK+Qa6qkecYXHC8i2nqKP46P5svn4w=    '

- AParamsList.Sorted = True  //This is the problem in ISAPI!! In SA Sorted = False

then, the line "AParamsList[i] := TURL.ParamsEncode(AParamsList[i]);" make a call to TStringList.put in System.Classes
procedure TStringList.Put(Index: Integer; const S: string);
begin
  if Sorted then Error(@SSortedListError, 0);
  --> error page:
Application Error
An unhandled application error has occured within IrisWEB
Error message: Operation not allowed on sorted list

Could you please verify why this different behavior?
Thank you
