Date: Tue, 18 Nov 2008 20:02:47 -0800 From: Bill Cheng Sorry, I need to be more careful. For "status files", I should have said: For "status files", a node has nothing should return a status response with no information *about files* returned. It should still fill the first 4 fields (UOID, Host Info Length, Host Port, and Hostname) in the status response. -- Bill Cheng // bill.cheng@usc.edu -----Original Message----- Date: Tue, 18 Nov 2008 19:52:12 -0800 From: Bill Cheng To: cs551@merlot.usc.edu Subject: Re: cs 551 question on tcp Oops! I didn't notice that the question asked about two things! Sorry! For "status files", a node has nothing should return a status response with no information returned. For "search", a node that does not have a hit should *not* generate a search response. -- Bill Cheng // bill.cheng@usc.edu -----Original Message----- Date: Tue, 18 Nov 2008 19:45:03 -0800 From: Bill Cheng To: cs551@merlot.usc.edu Subject: Re: cs 551 question on tcp Someone wrote: > Files can only be added with a store correct?
