What am I missing? CORS with VOLT

I may have a misunderstanding in how VOLT handles CORS and am not seeing it discussed in the forum.

I am building a proof of concept app that is making an a call to a remote server published to VOLT. In VOLT I have set the APP to allow the AJAX call to flow to any domain, but on testing the app I am getting the CORS errors. While VOLT allows CORS, is there some additional configuration needed somewhere else?

Here is the code, direct from the GetJSON example!

'GetJSON - gets some data from a site and processes it
'The data is a .json structure

Function Button1_onclick()
  GetJSON("https://somewhere.com/jasonhandler.php?Function=GetUser&Format=&APIKey=&PortalID=&Username=someuser&Password=somepassword", done)
End Function

Function done(data)
   Textarea1.value = data.Learner_LoginID & vbCRLF & data.Learner_LastName
End Function

You’re not showing the CORS message. Is it coming from the remote server (https://somewhere.com)?

Yes it is coming from the server. Apparently the server has to be allowed to support CORS as well? IIS has a lot of documentation to tht effect. I will give that a try.

Yes. It’s reasonable for a server to have limits on what other web sites are allowed to do with it.

I have this question also. Since cors-anywhere.herokuapp.com is no longer acting as a free reverse proxy, we run the apps locally using a chrome window that has CORS enabled (ie. Same Origin disabled). Works fine.

However, when we deploy to Volt and scan the QR code to run it on an iPhone, it doesn’t make the API call (says no data available). Thoughts?
