TBitmap is not Thread safe. So you must be sure that only one Session uses it at the same Moment

You can use Microsoft Edge browser for example. It has a setting, so that the user will be asked what to do with the file (i.e. "save as ..."). It depends on the browser, there is no other way.

It fetches / caches all the records on the server. If you use server cursor for db components the data is cached in db server, if you use client cursor the data is chached in UniGUI server. To the client (browser) is always sent one page.

You can use Microsoft Edge browser for example. It has a setting, so that the user will be asked what to do with the file (i.e. "save as ...").

Then try to use a callback...

No, the "OnClose" event with "action := caNone" works for me.

Sorry, this event is really only in the VCL, not in UniGUI. But on my older UniGUI version it works like expected with "action := caNone".

You could also try "OnCloseQuery".

Try UniQuery.SpecificOptions.Values['FetchAll'] := 'True';

I think it is a thread pool. Make a "sleep(15000);" after your line and call the app in another browser (tab). Then you should get another thread (id). But the thread id can be another on each call from one session.

Is your app 32bit? Then the max used size is 2 GB.

This does not Work. Try system32 or syswow64.

Where are the openSSL dll's located?
