Hello,

I'm just starting off using libcurl, and I'm trying to use it to make
WebDAV requests against a Microsoft Exchange server. Below I've
included an HTTP request, an HTTP response, and the C++ code I use to
generate these.

The problem is that my CURLOPT_WRITEFUNCTION callback method is not
being invoked when the HTTP response shown below is sent back by
Exchange. I've used Ethereal to capture these messages, so I know the
response shown below is in fact being sent.

At the bottom of this message is the C++ code I used to generate this
scenario. Note that when I run this, the "write_data has been called!"
text never actually prints out, and breakpoints inside that function are
never triggered. I'm building and running this on Linux FC4, and
curl_version() returns: libcurl/7.10.6 OpenSSL/0.9.7a ipv6 zlib/1.1.4.

Please let me know if you have any ideas of what I may be doing wrong!

Thanks,
Andrew
