The preview doesn't guarantee that the entire body is sent, right? I
need to see all of the payload...

Like what you said, it looks like this was the problem: The server was
responding with a 204 even when Squid's ICAP client did *not* send an
"Allow: 204" header in the ICAP request. It's too bad that Squid's
ICAP implementation doesn't generate an error message after receiving
a 204 when one is not allowed and preview is not enabled...

I'm fixing up my server now, so I can't guarantee that this was the
bug, but all signs seem to lead that way!

Thanks much!
