[jira] [Commented] (SLING-2320) Current DOS-prevention for infinity.json can prevent enumeration of children

["Jeff Young (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-2320?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13289232#comment-13289232 ] 

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

The 12/Dec/11 patch still needs to be applied.

Without it performance will be impaired (due to 2 exceptions being thrown per node and the result being serialized/de-serialized/re-serialized).

> 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).
