i am getting a tcp dump now, i will send it to you directly rather than to
the list. basically, 14 packets come in, then no more, and after the
timeout, libcurl returns. it likely could have returned sooner on seeing
the FIN's from the squid box

the config is pretty simple.

1. http server and libcurl client on same machine (ip ...7) fc2 linux box
2. squid on rh9 linux machine (ip ...9)

libcurl pseudocode:

headers = curl_slist_append(headers, "Expect:");
curl_formadd(...);
curl_easy_setopt(mycurl, CURLOPT_HTTPHEADER, headers)
curl_easy_setopt(mycurl, CURLOPT_URL...
curl_easy_setopt(mycurl, CURLOPT_HTTPPOST...
curl_easy_setopt(mycurl, CURLOPT_PROXY...
curl_easy_setopt(mycurl, CURLOPT_PROXYUSERPWD...
curl_easy_setopt(mycurl, CURLOPT_PROXYAUTH,
   CURLAUTH_BASIC|CURLAUTH_DIGEST|CURLAUTH_NTLM)
curl_easy_perform(mycurl);

squid is the stock compile that comes with rh9, but i added PAM to its
config. i can detail that if you need.
