Ryan, that's just what the problem is. I don't think this is a bug, so I 
didn't
file a bug report. The thing is that however rare it is, some of us do 
sometimes
need to change the URL of an already running blog(as I recently shifted 
one
of the blogs that I manage from a sub-domain on my site to its own 
domain).
Now the problem is that the URL can be changed in the DB dump via a Text
Editor or via any DB editing tool and the blog will run fine, but with 
cacheing
the problem was that the URL gets hard-coded in the cache files. Now I 
use
WP-Cache2 and that gives an option to clear all cache files from its 
Option page.
But there is nothing of this sort of WP's inbuilt cacheing, so the 
problem. Though
it can be contested by saying that the cache can be deleted manually 
using an
FTP program since the user moving the blog will definitely have access 
to it
but I thought that I should raise this here as well so you guys can put 
an option
in the WP-Admin to enable/disable and flush cache.

wp_cache_flush()

thanks for the tip, I've this saved in "Most Important Tips" now!! :)
