I think it's not an IDEA but, the CA Support team said it's an IDEA.
- When access by url https://tenant.portal.com/XXXX (almost undefined url), the portal displays the proper 404 not found page.
- But, when .../adminXXX, the portal displayed the default jetty engine error page with specific version.
The security department of the customer have concerns about leaking server information by lack of handling errors.
I should meet the customer requirements but feel powerless.
So.. Please Help. Vote for me.
