Motivation
A surprising oversight, we were never setting the
content-lengthheader when sending out a known-length body.Some transports might be already doing this, but this change makes things more consistent.
Modifications
Add the
content-lengthheader when setting a body and we know the length from theHTTPBody.Result
More consistent experience.
Test Plan
Adapted unit tests.
