Steve is correct - if done correctly, you should not lose any SE
standings.
As to the source, I am trying to locate it - Google's advice to
webmasters recommends using the "301 Moved Permanently" method but (1)
for many people this may not be an option, depending on their host, and
(2) I don't like it as much because it isn't as informative to visitors.
You can have a look at an example of how I've implemented the refresh
tag at
http://www.psychlinks.ca/psychlinks.htm - this has the advantage
of telling visitors what's happening and reminding them to change their
bookmarks and it provides the delay preferred by some search engines as
well.
There is a definitive source for the 10 - 30 second guideline (one of
the Search Engine gurus, a female I think, maybe Jill Whalen or Shari
Thurow...) but I'm having trouble locating it right now - in the
meantime, here is another article that make the point and gives the
rationale:
http://www.search-marketing.info/meta-tags/meta-refresh.htm
Also note that if the Refresh value is low (e.g., 1-4 seconds) it
effectively disables the back button which is going to annoy your
visitors - and annoying visitors is not usually the point of a website,
especially a commercial site!

Hi David,
Is there an authoritative reference for this comment?
If you're moving your site from one domain name to another you've
hosed your search engine standings in the any case.
