using redirects?

[Slade]

In the thread "seo for BIG companies"(http://www.webmasterworld.com/forum34/260.htm [webmasterworld.com]), NFFC posted this message:

"Instead they have ordered 20,000 pages with a javascript redirect to their site, pages so ugly that no-human should ever see them."

I am a casual optimizer, normally just keywords, some content reorginization, and titles.

This doesn't make any sense to me, and I'm trying to figure out where you'd put something like this?

Would it be added to their existing site? Set up on a new domain name for them, as a passthrough? An existing domain?

PS: I know this is a somewhat sticky topic. I'm not looking to try it, just to figure out why its useful.

Slade, I can only guess because I've stayed totally clear of JS (too many browser crashes for my liking), but I'd imagine it's pages that are served up to search engines for rankings. Then, since spiders don't follow JS redirection but browsers do, surfers are redirected to the actual sites.

I surmise this because I've seen pages in the Google cache that did just that.
