What is Alexa's spider called

[lloyd]

Hi

Can someone please tell me what Alexa's spider is called and how it is recorded in your logs.

Thanks.

PS If you know the name of AOL's as well that would be useful.

ia_archiver , it doesn't follow robots.txt , it doesn't follow links, I don't know how it hits certain pages of my site when it is not linked to any other pages.
