[wp-hackers] Force a new ABSPATH when moving WordPress?

[onlyunusedname]

Excellent.  Thanks, Otto.  There is eAccelerator running on this server and
clearing its cache is just the trick.

Just out of curiosity:  If one wanted to write a script that did everything
in a more environment agnostic fashion, would that be possible?

In other words, this script would run once after a URI change and it would:

1) Change the relevant database entries from $old_url to $new_url.

2)  [Magically solve a cached ABSPATH problem in a reasonably environment
agnostic fashion]

3) Redirect to $new_url  (Site successfully moved.)


Is step 2 as preposterous as I am making it sound, or can you imagine a
feasable-ish answer?

Thanks in any event.  You helped me a ton.
