Jeff Young commented on SLING-2320:
-----------------------------------

Felix, your change to the logic turns off the DOS limitation for infinity as 
well (which is encoded as -1).  The second half of the if stmt should be != 1, 
not > 1.

I've just finished writing a unit test for the servlet, so I'll go ahead and 
fix this as well in the patch.  I'm planning to upload two separate patches: 
first the unit test (with this fix in it), and then a cleanup of the exception 
behaviour.  Sound good?

> A request of resource.1.json should always succeed, as it's the primary 
> method for JSON introspection of the repository hierarchy.  DOS protection 
> should only apply to "deep" traversals; that is, anything with a depth 
> greater than 1 (and, in particular, resource.infinity.json).
