handling HTTP redirects

Of course the Vizier people can use redirects if they want, it is quite 
legal. It is also legal to make a cone search which never returns more 
than three sources, or one that returns an error for every possible request.

I have done a rough timing test of Vizier cone searches, and I find that 
the redirect costs about 0.5 seconds per cone search. In other words, a 
Vizier service will be quite a bit faster if you simply replace up front 
the string "vizier" with "webviz" in all the accessURLs that you get 
from the registry. Since Vim runs hundreds of cone searches at a time, 
this is what I have chosen to do, to save a few minutes of my customer's 
valuable time.
