First it read robots.txt with UA "lwp-trivial/1.38", then it took the main page and two stylesheets with UA "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.1.4322)". All requests were HTTP/1.0.
One stylesheet is a special MSIE-stylesheet, pointed to by a conditional-comment ([if IE]) in main page. So this bot seems to be a real MSIE.
The other stylesheet contains an import-rule, but that import-file wasn't accessed?! So this bot isn't a real MSIE 6.
Time delays are strange, too: robots.txt at 19:11:06 main page at 19:12:08 two css files at 19:12:52
