Re: HTTP in NS

[Haobo Yu <haoboy@isi.edu>]

(1) MOD means that server modified a page. Its fields are:

  S & MOD & p \tup{PageID} m \tup{ModifyTime} n \tup{NextModifyTime}

It shows the modification time and the next scheduled modification time of
a page. 

(2) To build a cache hierarchy, you first connect caches then set parent:

	$cache_(2) connect $cache_(0)
	$cache_(2) set-parent $cache_(0)

Then you need to attach a server somewhere in this hierarchy, which can be
done using 'connect'.

Hope this helps.
