Hi all!

I've developed an application based on libcurl.

I've two network environment:

1) libcurl ------> SQUID Proxy ------> IPlanet Proxy ------> Internet
2) libcurl ------> IPlanet Proxy -----> Internet

I use Visual Studio 6 on a Windows 2000 with libcurl 7.11.

My applications perform 2 operations in the following order:

1) POST
2) MULTIPART POST

Both the requests goes to the same internet address through the same proxy.
The protocol is HTTP (not HTTPS).

If I work with the first environment (through the SQUID PROXY) everything
works.

If I work with the second environment (directly through the IPlanet Proxy)
the MULTIPART POST returns with an Empty Reply from server.

If I do exactly the same operations with HTTPClient (an HTTP client library
for JAVA) everything works.

Here is what I see if I turn on VERBOSE:
