Would it be useful to at least try the www. and non www. variants 
when the one given fails, before giving up?

I assume trailing "/" is already stripped of before the string 
comparison?  If not, that's definitely needed.

And it seems that a HG lookup that subsequently fails to complete the 
teleport is still cached.... that was the issue I had in testing with 
Fred in the last few days,.  I had to do a 'show hyperlinks' and 
'unlink-region <region-domain:port/>' to  allow subsequent teleports 
to work.  This means its only open to someone with a region server 
and console access. A normal user could not have fixed this. If 
possible that failed teleport should lead to the cache entry not 
being made.. or deleted from the cache if it was already in place?
