Has IIS changed the way XMLHttpRequest work on Windows Server 2022 Standard?

Question

I got some sort of messages regarding the use of Cross-Site webapps and how they interact. We use a frame on which we use the API components over Port and somehow we currently send the port over XSRF token in a non secure way. The thing is that IIS answer the Client request with the Domain and the accessed port which in this case is dynamic, ironically it only happens when we use Dynamic ports (1500>).

Any thoughts?

Answer 1

Exactly, it happens at IIS level. From what I got doing my research. I found that there would be any missing Plugin related to CORS or URL rewrite. Will advocate to other forums as well.

Thanks for the prompt reply.
