Maybe. With a CONNECT squid cannot (yet) intercept the encrypted
transmission. So I don't think its likely to get logged beyond the amount
transfered. In this case I think 242648 bytes.

Or, the webserver may be sending the error page and not sending special
garbage to override the IE (un)friendly 404 page.

Could be on the web server. I know many dynamic server systems limit
between 10 and 32MB by default.
