Alexander Klimetschek commented on SLING-1308:
----------------------------------------------
Just to clarify: this patch does not set the Location header (AFAICS), but
simply returns the possible URLs like /.1.json, /.2.json, etc. up until the
maximum depth that returns a number of nodes below the configurable limit.
But there seems to be a bug in the latest patch: allowedLevel should be
decremented in the loop, otherwise it seems endless:
+ while (allowedLevel >= 0) {
+ writer.value(r.getPath() + "." + tidyUrl + allowedLevel +
".json");
+ }
> Node.infinity.json contains risk for DOS.

> As it is now any user can do a node.infinity.json .
> If this happens on the root node in a repository with many items, it will
> cause the server to slow down (eventually crash?)
> I've created a patch confirming the discussion @
