Information question about DfsImpl class

[Dirk-A]

Hi,

In the getLinkReferral method, in case of domain referral this line of code:

link = path != null && dr.getPathConsumed() > 0 ? path.substring(0, dr.getPathConsumed()) : "\";

determines the new deferral link, but in some cases it returns the parent folder of the actual intended folder. It is caused by taking a substring of the current using the dr.getPathConsumed()
Question: can anyone explain why a substring is taken at this point? How is dr.getPathConsumed() constructed?

Tnx in advance

dr.getPathConsumed() provided by the server to indicate how much of the requested path is replaced by the referral target.

E.g. if you have \domain\dfsroot\some\subdir\foo\bar and a DFS link is configured for \some\subdir to e.g. point to \server2\share\other\dir:

pathConsumed returned in the refereral should be len("\some\subdir"), the client can then determine that a) the redirection should be applied to the resources below that path (stored in link for caching), and also the remaining path \foo\bar that indicates the portion that needs to be appended to the referral target, \server2\share\other\dir + \foo\bar

If the parent folder in that case is the path for which the DFS referral is configured, that would be the expected behavior.
