Is it true that spiders and bots don't like document-root or relative paths? I read it somewhere just now; and I don't know whether "don't like" means a spider will act as if there's nothing there and prompty leave; or feel somewhat offended, but compensate and carry on...
Do spiders go in circles? If all my pages have at least one "go back up one level" and lots of "go down some levels", are the bots clever enough to remember where they've been? If they're not... can I tell a spider to ignore just some links on a page?
