But this can only happen due to a timeout, when static redirect kicks in, right? > xrdfs should work with or without '-d' option, no? Sure should ... but it was timing out for me for some reason (authenticating to redirectors at some level, I assumed ... but could be something else) and I thought this was also the reason why Yujun was getting an empty response for some queries. So I guess we should figure out where the timeouts / delays happen and why.
