Hi Daniel.

In the past e-mail, I gave you some wrong information.

My application does two MULTIPART POSTs.
The first one sends a small amount of in memory bytes.
The seconds one sends a file (500KB).

The JAVA Application does exactly the same operations.

I've trapped the communication between my JAVA application and the server
and the communication
between my CPP application and my server with ETHEREAL.

I've used the function 'FOLLOW TCP STREAM' to save the result.
The get the whole communication of the JAVA version, I needed to follow 3
differents streams.

Attached you'll find the result.

Thank you in advance,
     Massimiliano Ziccardi

(See attached file: cpp.log)(See attached file: java.log)

Using ethereal, I've trapped the communication between my application and
my server.

Can you figure out why the server (or proxy) doesn't send a response? If
you
have access to logs on any of those they might offer clues.

Can you get a similar dump from that and compare how the data is sent? You
can
also use CURLOPT_DEBUGFUNCTION to get a full trace of every single byte
libcurl sends and receives.

Since it works over one of your proxies, since it works for most people and
since it works in test cases all the time, I kind of lean towards that your
proxy is doing something unorthodox.

(I take it "libcurl 7.11." means 7.11.1?)

This line wrap was made by your pasting, wasn't it?
