I presume you're talking about Content-Length: in the request headers?

Can you show us how to reproduce this? Are you using a multi-pass
authentication perhaps?

I don't understand that is. If the applications sets what? The Content-Length:
header? That's generally not adviced and is very rarely the correct answer to
anything.

I don't understand this either. You wanted to send a PATCH request body
*without* setting POSTFIELDSIZE ? If so, how did you expect libcurl to figure
out the correct size?

Also, please tell us what curl version you're using.
