If you can modify/configure the first ICAP service to _annotate_ the
transaction (via ICAP and/or HTTP headers that would mark the response
as virus free/infected) instead of generating a brand new HTTP response,
then you can still chain your ICAP services and feed the (mostly or
100%) virgin response to the second service.

Yes, but only using a custom "broadcasting" ICAP or eCAP service. You
would have to write such a service yourself (or purchase it). Squid does
not come with one. From Squid point of view, there will be just one
service to deal with in this setup.
