Thank you that helped stopping the processes although it took a couple hours for the processes to disappear

So the normal IRIS Version does not support IntegratedML? 
Why is this not mentioned anywhere in any of the documentation? 
Can I install the ML Version over the normal one? 

I installed the instance myself via the 2023.1 installer and then upgraded it to 2023.3. 
I always make sure to check every component when installing, so everything should be there. 

I did not change any configuration as the Documentation says

"Upon installation, %AutoML is set as the system-default ML configuration. You can use IntegratedML without any adjustment to your configuration necessary." 

the following query resulted in 0 rows SELECT * FROM INFORMATION_SCHEMA.ML_TRAINING_RUNS

It states IntegratedML, is there a seperate one for AutoML?

After talking to our Intersystems contact, this seems to be the only reasonable solution. As far as I understand it, with this license there is no session limit. 
Thank you for your suggestion.  

Yes this was indeed a Typo thanks for the info. I corrected it, but no change sadly. 

This text mentions that requests will be treated as concurrent users with multiple connections. This would be totally fine, if I managed to send the SessionID Cookie so the system recognizes multiple requests coming from the same user. 

However, each request is treated as a new user, as I am unable to send the cookie with XMLHttpRequests whereas the CSP.Broker Method is able to send the Cookie.

Okay I will try my luck with a workaround. Thank you for your help. 

I'm a little confused now... 

When talking about a normal external Apache server, you would only need to add a couple of Cypher Suite Keys and change the protocol version. 
Intersystems Webgate also uses Apache Web Server as far as I can see in the Webgate Management. 
How come I need to add python code to my application in order for a browser to send its request via HTTP/2? 

I'm not really that well trained in server management but I feel like there is something I'm missing here. 

Why is the application responsible for the request instead of the apache server? 

What kind of adjustments would be necessary to change to HTTP/2/3. Is there any documentation for that?
