[undertow-dev] undertow is redirecting?

[Jason Greene]

Hmm we should be handling this outside of the default servlet though. Check out this specific example in 10.10

"A request URI of /catalog/products will be redirected to a URI of 
/catalog/products/.
■ A request URI of /catalog/products/ will be passed to the “default” servlet, if 
any. If no “default” servlet is mapped, the request may cause a 404 not found, 
may cause a directory listing including shop.jsp and register.jsp, or may 
cause other behavior defined by the container. See Section 12.2, “Specification of 
Mappings” for the definition of “default” servlet."
