Re: [Handle-info] resovleHandle method query

[Sean Reilly <sreilly@cnri.reston.va.us>]

Hi Scott,

You are right that that method is supposed to return an empty array if  
the handle exists but has no values of the specified types.  This  
might be related to the server since they list of types are sent along  
with the resolution method.  Can you examine your access log to see  
what response code is being returned for that query?  That should  
indicate whether the server is responsible for the "handle not found"  
response or if it is a bug in the client.  I suspect that it is  
something on the server side, especially if your server is using  
something other than the default handle storage component.

Thanks,
Sean
