S/4 OData Service with SSO Caches Previous User

[tokgozatakan]

We have an SSO scenario maintained and sending out POST requests to our custom OData Service in S/4HANA.

The issue is the following:

1. USER A sends out the POST Request; Document Created Successfully (created by is USER A)
2. USER B sends out the POST Request; Document Created Successfully (created by is still USER A)
3. USER C sends out the POST Request; Document Created Successfully (created by is still USER A)
4. When we check /IWFND/TRACES we see that all the requests are falling under USER A

Somehow, S4 is caching the user authorization information and reusing the same user. Is it possible to disable/clear this caching?

The problem was actually related to the sender, where the cookies were cached so all the other requests were being signed in with the previous user.
