Dear,

On a huge system with sometimes few hundreds users I got the error "Session has no active form". I have no clue what this is. The stracktrace does not show any user code. Any hints? 

If I call the same page again everything works.


Best regards
Sven

I have tried googling the answer, but I cannot seem to find anything.

Does IntraWeb have built in defenses against click jacking? or is this something that I have to implement?

Hi Alexandre,

I have installed my own NOT FOUND HANDLER (404) to prevent scraping.
When a user searches entire directories for files, after a certain number of times the user's IP address is temporarily blocked.

I have now discovered that the NOT FOUND HANDLER is no longer called by the server when file extensions are blocked.
Instead, a session is created and the server blocks after a while.

Could it be that the handling has changed in one of the last versions?

Regards

I have a frame that is created on a form. Is it possible to async refresh this frame ONLY (not the whole form) from within the frame code?

Thank you

Hello

I'm a newbee in IW programming and so I started with IntraWeb14.
I want to make a form with a Menu on the left side and dependet dialogs or lists on the right side of the form.

Normaliy in CBuilder or Delphii I take a Panel on the left to place the menue in it and a frame on the right side for the depending content.

I read something about a component TIWFrame.
But I cannot find such a component in IntraWeb 14 to put it on a form and load the frames .
I search in the online doc, I make a textsearch on all hpp files , but I cannot find it.

Is is an old component and disabled in Version 14 ?
And what can I do, to create these simple app ?

Thanks

Hi,

Scenario:

In a project I am working on, we use hardware devices running a webbrowser as a display but no touchscreen, mouse or keyboard attached.
They are configured to load a webpage https://webserver.local/externaldisplay
The page https://webserver.local/externaldisplay is handled by a TContentForm in a IntraWeb application.
That page contains a TIWMonitor to poll the server and act based on the response.
When there is a network error or the server is stopped, the client should display a message informing the user of the device.
When the server is restarted the communication has to be restored. No user intervention should be necessary.

Part of this is working.

* After starting up the device, a session is created and the page is loaded via the content handler
* The page is refreshed based on the TIWMonitor response
* When I close the server, a message is displayed in the browser
  TIWMonitor.jsCallbackName gets called with value as a parameter. value == -1 when the server is gone.

But when I restart the server, the value keeps being -1. Reason is the old session does not exists anymore.
What should I do to create a new session on a $/QueryStatus call?
Or in what other way can I get the client to keep working after a server restart?

I have to check the IP from the client before allowing access to a page.
I test this in TContentForm.OnBeforeExecute and would like to return 403 Forbidden

Result is the exception 'Reply type already set.'
