Dear Curl users,

curl 7.10.2 (i686-pc-linux-gnu) libcurl/7.10.2 OpenSSL/0.9.6g zlib/1.1.3

My problem is that I have troubles posting larger files to an IIS-5 server
over HTTPS.
I have tried to lower CURL_MAX_WRITE_SIZE to 10K and then to 1K, but that
didn't make any difference, although it looks like SSL_write() was the
issue.

I've noticed 3 different behaviors:

1. file size 3.5K, no errors, i.e. I don't get any "Send header, 0 bytes"
2. file size 1 MB I get a lot of "Send header, 0 bytes" messages, but curl
recovers and POSTs file successfully.
3. file size 6.6 MB I get the error below and file cannot be posted .

/opt/curl/bin/curl -s -w "HTTP CODE IS %{http_code}" -A
"Mozilla/4.0" --trace - --data-binary
@/local/ftp/secure/edi_customers/foo/outbound/myfile
"https://data.foo.com/dx/automated/FilePost.aspx?Username=****&Password=****
