question on https through proxy

Hi, I'm trying to debug a problem with an https connection through a
proxy. Not sure if it is a curl issue or proxy issue, looking for any
ideas. http connection through the proxy works fine and an https
connection from ie works fine, but https from curl hangs.

proxy output from ie connection says:

accept connection ... scan: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0;
Windows NT 5.0) default
scan: Host:
scan: Content-Length: 0
scan: Proxy-Connection: Keep-Alive crunch!
scan: Pragma: no-cache
connect to: ... OK
<data follows>

proxy putput from curl connection says:

accept connection ... scan: User-Agent: curl/7.9.8 (win32) libcurl 7.9.8
(OpenSSL 0.9.6d) default
connect to: ... OK

curl says:

* About to connect() to
* Connected to ( port 8000
* Establish HTTP proxy tunnel to

And the connection just seems to hang. https to the server from curl
bypassing the proxy also works, so it seems to be a specific interaction
between curl and this proxy using https.

Any ideas?
