Hello,

My web server is installed on a Robot which for security reasons cannot be connected to the web.
I used the “MultiSessionssNoCookie” example to display a data grid:
With web access

  /// <summary>
  /// Add the files for the grid
  /// </summary>
PageContext.AddLinkFile('https://cdn.datatables.net/1.10.19/css/jquery.dataTables.min.css');
PageContext.AddScriptFile('https://cdn.datatables.net/1.10.19/js/jquery.dataTables.min.js');
PageContext.AddToInitProc('$("#tbl1").DataTable();');

It works perfectly.

Locally, with files in:
/bin/wwwroot/css
/bin/wwwroot/js
  PageContext.AddLinkFile('/css/jquery.dataTable.min.css');
  PageContext.AddScriptFile('/js/jquery.dataTables.min.js');
  PageContext.AddToInitProc('$("#tbl1").DataTable();');
I have the following error
"class EIWinvalideRessourceException IW_JS_jquery.dataTables.min not found"

Thanks for your help

Hi Everyone,

I'm using Intraweb for 2 Years now, I found this software very useful for my projet.
I have a little problem when I'm trying to open my website from a link outside from Webbrowser (mailbox for exemple), That create always 2 sessions !
I try other examples from Github (ContentHandlersDemo or MultiPageApp) I have the same behavior ! 
How could we make to get only 1 session ?
Thanks for your help

with Intraweb I have a timer which checks every minute to see if the data the user is viewing has changed and a page refresh is required. What code should I use to trigger the refresh. I understand that a component on the form can have its click event executed, but how is that done. I have seen some ideas about WebApplication.CallBackResponse.AddJavaScriptToExecuteAsCDATA but not sure how to use it. Help will be appreciated.

Hi All,

I don't know if anyone has encountered the same challenges as I have, but here it goes.
After upgrading my webserver to Windows Server 2022, my Intraweb applications using TIWAppCache stopped working.

More details:
I create a new Tempfile with: LFileName := TIWAppCache.NewTempFileName('.pdf')
The App does it's thing and saves it's data to this new Tempfile
Finally I process the Tempfile with: HRef := TIWAppCache.AddFileToCache(WebApplication, LFileName, FContentType, ctSession)

But in one of the 2 final steps I get the error: Can't add file <TempFile> to cache. The file does not exist.

All this is done in HTTP.SYS.
When running the same app in SA, all works fine.

I've read about security issues and patches on Windows Server 2022 regarding HTTP.SYS, could it be that this mechanism is unsecure?

I'm using Delphi 11.1 with IW 15.2.68 Ultimate.

Thanks in advance for (possible) solutions!

Cheers, Paul

PS. After moving everything to a Windows 2019 Server, all worked well!

Under IIS/ISAPI, this worked for me practically out of the box. But with HttpSys I do not seem to be getting any client certificate data.

1) Certificate installation IW app does not enable "clientcertnegotiation" httpsys parameter, which is off by default, so one has to manually run "netsh http update sslcert [...]" command in powershell to enable it. DONE!

2) Then you need to add ServerVariables.Add commands in BaseConfig. DONE!
3) And finally read the data using WebApplication.Request.GetServerVariableValue in the form event. DONE!

The client browser does get a prompt and confirms it, so the server must be asking for it. But the data read back is empty.

I suspect this may just be an omission in the IW httpsys implementation.

Is anyone doing this? Is it working for you? Have I missed anything?

We have a application written in Delphi 2007 with IntraWeb 8.  We are trying to deploy it on a web server running Windows Server 2019.  The application appears to work at first.  But after a short time and with a few users accessing, we appear to start to have application errors occurring when the application attempts to access Session data from IWApplication.SessionsList.  I'm wondering if anyone has ever successfully deployed an IW 8 Application on a server running Windows Server 2019?

Thanks for any help anyone can provide.

During the operation of the program, the text of the link is formed, which you need to direct the user to.

procedure GoToLink;
var
mLink : String;
begin          
          mLink := CreateLink(mParameters);
          ???
end;

Please tell me how to do it?

I point out that on the documentation page "https://www.indyproject.org/documentation/" the download links do not work, for example "http://ww2.indyproject.org/downloads/IndyDocs_10.1.5.0_HtmlHelp.7z" (DNS_PROBE_FINISHED_NXDOMAIN).

Am I doing something wrong?
Thanks

I've just realised that in HttpSys services, there are no Applications, and no Windows forms, therefore no way to listen for any windows messages. There are even no TService descendants.

Has anybody else run into this? What did you do?

Hi,

I have many variables declared as public variables in the UserSession. It is used to keep session-specific variables. They can be accessed fine within the UserSession unit, other procedures and functions can be accessed as well, but I'm getting an "Access violation" when trying to read any of these variables from another unit.

This was working fine in IW14, but not after migration to IW15

Any idea what is going wrong here?

Thank you
