EBay bidding problems with squid2.2-3 transparent proxy on linux. HELP!

i'm using squid-2-2 rel 3 on linux kernel 2.2.7 and doing it with
transparent proxy mode. everything works PRETTY good and the cache has
been running for weeks on end serving up quite well. only problem, when
users who are routed through the cache try to bid on ebay items, it only
send half of bidding response page with the garbled html source at the
end. it _sometimes_ works after 5 refreshes on the browser and every
once in a while. my config is very basic without many config options set
(although i've run squid with a very configged and it reponds very
similarly) <sp?> i've got cgi-bin, ?, cgi, dll, and ebay in the
heiarchy_stoplist and no_query ACL. and no luke, i've tried it with a
couple variations of this and still no solid response. hope you can help
out. also, the "whitespace" in the uri. what is the default and i'm
presuming i should 'allow' it and send the whitespace through. thanks

            -peace, thanks - chris
