The url is entirely up to you. It is the URL of the script that you
write to be the Ajax backend: you can call it what you like, and put
it where you like (though it introduces many problems if it isn't on
the same domain as the script it's being called from).

I don't know Rails, but if it's anything like symfony, a partial isn't
enough: it needs to be its own page, which will parse the arguments
from the query string, generate the output, and send it with the
proper headers. It could be bare text, XML, HTML or it could be empty
and return the data in an X-JSON heaader. But if you're going to use
Ajax.Updater, you need to return an HTML fragment (not a whole HTML
page). In any case, though, it needs to have suitable HTTP headers.
I'm guessing that Rails has a way of creating a page which only
returns the headers and text you want.
