I've seen something similar whereby HTTP attack traffic which has been deliberately constructed to be non-cacheable has been relayed from a CDN to the targeted site. Have you looked into your HTTP query details in order to see if you're getting lots of queries which stand out in that regard vs. your regular traffic? Another possible cause would be changes to a site itself which results in more non-cacheable dynamic content which can't be served via the CDN. ----------------------------------------------------------------------- Roland Dobbins <rdobbins@arbor.net> // <http://www.arbornetworks.com> Luck is the residue of opportunity and design. -- John Milton
