Hello,

We have IW 14.2 along with XE5.
Our html contains DataTables plugin.
Tu supply data to DataTables we're trying to use a Delphi function but we don't know how to make the function to return this data to the DataTables js function.
We cannot find a way to register either a callback real function (not a procedure), or to pass out/var parameter(s) from the procedure.

Any help, example, demo will be much appreciated!

Thank you

This post is a copy of the one I just posted on the Embarcadero forum.
Just want to see how it works here.

----
I am stumped by this.

I have my Windows client using IdSMTP to connect to my Linux EXIM4 server.
This always works perfectly.

I copied the entire unit over to my new Android App, that is, I copied the .pas file, and I made a new FMX Form for it on which I copied the exact same selection of SMTP, SSL and SASL etc. components.
I have set these up on the Form in exactly the same way.
Added the same 3 SASL Mechanisms in the IdSMTP and in the same order.
As far as I can see it is all exactly the same.

{code}
   SMTP: TIdSMTP;
    IdSSLIOHandlerSocketOpenSSL1: TIdSSLIOHandlerSocketOpenSSL;
    IdUserPassProvider1: TIdUserPassProvider;
    IdSASLPlain1: TIdSASLPlain;
    IdSASLSKey1: TIdSASLSKey;
    IdSASLCRAMMD51: TIdSASLCRAMMD5;
    IdSASLCRAMSHA11: TIdSASLCRAMSHA1;
    IdSASLLogin1: TIdSASLLogin;

  procedure:
 (Note this works perfectly under Windows)
            if UsePLAINSASL then
            begin
              if Superuser then LocalLog('UsePLAINSASL: Logging in with Username='+AUsername);
              SMTP.Username := AUsername;
              SMTP.Password := APassword;
              IdUserPassProvider1.Username := AUsername;
              IdUserPassProvider1.Password := APassword;
              IdSASLPlain1.LoginAs := AUsername;

              SMTP.AuthType := satSASL;
              SMTP.UseEhlo := true;

              IdSSLIOHandlerSocketOpenSSL1.Port := APort;
              IdSSLIOHandlerSocketOpenSSL1.Host := AHost;
              IdSSLIOHandlerSocketOpenSSL1.ReadTimeout := 10000;

              IdSSLIOHandlerSocketOpenSSL1.SSLOptions.Mode := sslmClient;
              IdSSLIOHandlerSocketOpenSSL1.SSLOptions.Method := sslvTLSv1;
              IdSSLIOHandlerSocketOpenSSL1.SSLOptions.SSLVersions := [sslvTLSv1];

              SMTP.UseTLS := utUseExplicitTLS; // utNoTLSSupport; //
              SMTP.ValidateAuthLoginCapability := true;
            end else
{code}

But the Android system fails with a: "Doesn't support AUTH or the specified SASL handlers!!"

I use the Android-type OpenSSL libraries, which are loaded correctly (and which are also used by the an IdTCPClient when connecting to an IdTCPServer)

When I look at the debug output of the EXIM Server, it seems to me that the SASL authentication HAS in fact finished, because the Server is already in TLS mode and is waiting for its first TLS packet. Which it never gets.

The Server shows this:

Hello,

-How to close (Killing it) the usersession if the page or the browser is closed ... ? 
(in the case the user don't use my own close button...)

With best regards
Mikey

Hello

Is is possible to get a list of active sessions?

The reason for my question is that i found that there  are orphaned files related to expired sessions that was not deleted, and i want to create a periodic clean-up process to delete files not related to active sessions.

PS: My files are stored in application directory with the session ID name.

Hello,

Right now when an Exception is thrown the OS instantly closes (if it is not in a try catch block). This makes it difficult figuring out where the error is coming from. Is it possible to somehow show the error before closing (in the console like in a normal console application or in the debug output)?

Hello Everybody !
I'm new on Intraweb, and I try to build my first application.
I'm on Delphi Tokyo entreprise, and I've upgraded my bundle version with the last one of Intraweb...
I try to use TIWAutherINI but I don't succeded to get it run... Nothing happens..

I've placed the component on the ServerController, Placed the property AuthBeforeNewSession to true, and link the Auther property to my component...
I've also placed a ini file named #Auth.ini in the same directory of my application...
The ini file is build like this :
[USER1]
PASSWORD=USER1PSWD
[USER2]
PASSWORD=USER2PSWD
....

I run my application, but nothing happens for authentification...
Where I could find documentation or sample to use those components , please ?

With Best Regards,
Mikey

I was wondering if anyone is using any anti-caching techniques for security reasons that they could share.

Hello,
if I change the destination folder of the application, in the project configuration, I have an error when starting the program
example:

  by default the directory is. \ $ (Platform) \ $ (Config)
  if I select. \ # bin \

here is the error displayed by the web browser
404 - Not found
Resource not found in RT9Intraweb




Delphi Tokyo 10.2
Intraweb 14.7.2

I have a few more questions that I need to look at for soc2.

1.  What type of session haijacking/cloning detection does IW have? 

How do the servercontroller->securityoptions work?

CheckFormId
CheckSameIP
CheckSameUA

And what does the program do if you uncheck ShowSecurityErrorDetails?

Do these errors get logged somewhere?

hi, i use iw 14.2.7 and have a problems with sessions. for any reasson hang up my app and try from the button of server SA "Reset Sessions". but when try open the browser again and run my app in the server SA appear the sessions connections where i suppose reset with the button "Reset Sessions".
