That will work fine, although there are more efficient ways to do this.
I think this will actually be a fairly common use case, so I have added 
a handler to handle this:

https://github.com/undertow-io/undertow/commit/04385f29996673658bce3c131de4e0a32241e78e#diff-3 


Basically it matches requests based on a combination of method, path 
template and predicate, and will be considerably more efficient that 
testing a list of predicates.
