    if (queries.query_identifiers [0] in queries) : 
        log.debug ("Received the client's list of requested blobs") 
        d = self._get_available_blobs (queries [self.query_identifiers [0]]) 
        def set_field(available_blobs) : 
            return { 
                'available_blobs' : available_blobs, 
} 
d.addCallback (set_field) 
        return d 
return defer.succeed ({ 
        
})
