I have a Java application running under Tomcat 9. One component of this application is OpenID authentication, in which my application is a relying party.
It sends a POST request to https://login.microsoftonline.com, but in one scenario I'm getting an error back from Microsoft. I need to see exactly what was sent in the POST request including the POST payload data. Is there a way of doing this? I tried the requestdumper filter but I don't see anything useful.
