Hi Mark,
Thank you for your reply.
For use-cases where we might not have (easy) access to the Tomcat-server
config in the run environment:
Is there a way to access the Connector object, or a different solution inside
the Servlet to raise this limit to circumvent possible problems when upgrading
to 11.0.8/10.1.42?
Best,
Fabian
