Class DownloadGateKeeper

java.lang.Object
  com.atlassian.confluence.security.DownloadGateKeeper

All Implemented Interfaces:

GateKeeper

public class DownloadGateKeeper
extends java.lang.Object
implements GateKeeper

GateKeeper for the Confluence downloads directory.

Any resource granted permissions for will be normalised to remove any part of the path before the first occurrence of the text download. So /confluence/download/foo.txt will need to be checked as download/foo.txt. Attempts to grant permission to a path that doesn't contain "download" will throw an exception.

Permissions will be expired 24 hours after they are granted.
