Hey all,
Been a while, hope you remember me. :)
We're using cURL these days to do a POST of form data. When combined with proxy
authentication and ANYAUTH behavior, there's a bug with rewinding the input
data. Here's some source snippets:
if (curl_formadd(&xfer->uploadForm, &formLast,
CURLFORM_COPYNAME, fieldName,
CURLFORM_FILENAME, fileName,
CURLFORM_STREAM, xd, // a pointer to an
internal structure that is supported by our READFUNCTION
CURLFORM_CONTENTSLENGTH, len,
CURLFORM_END) != 0) {
goto out;
}
When sending this using ANYAUTH and receiving a 407, we try again after setting
the proper proxy credentials, but the file is already completely read from the
first request and not rewound due to this code, so the attachment is blank. We
thought it was because we don't have a SEEKFUNCTION, but defining it did not
help because of the logic in Curl_readrewind.
Is there any reason *not* to rewind the file in this situation?
Thanks!
-Josh
