Know any good spiders?

[Frank Cervone]

Hello Web4libites,

Does anyone out there have experience with spider (or spider-like)
programs that validate the URLs on your site's pages? Any info will be
appreciated. Even if you are using a manual system, I'd like to know the
implementation details. Please respond to me directly, and I'll summarize
the results for the list.

Thanks,
