IE's digext

[keyplyr]

I have read that 'digext' is the crawler for IE's "make available offline" mode - used in IE's subscriptions as well. When going through server logs, I see it often in a visitors UA string. Would that necessarily indicate that this user is downloading the webpage for offline access, or just has that function enabled? What would change in the log entry if the user was downloading the webpage for offline access using this utility?

Thanks

I think the same "spider" is used when saving the Web page too...

Using IE6, I used the "make available offline" mode to save my site to desktop, opened it and browsed around, waited a few minutes, then downloaded the access_log and found my event. No 'digext' in my UA string - so there must be more to it than that.
