# Steps to reproduce
Simply post a JSON with HttpClient with NSUrlSessionHandler .
# Expected behavior
HttpClient with NSUrlSessionHandler should set Content-Length header on POST as before
# Actual behavior
HttpClient with NSUrlSessionHandler doesn't set Content-Length header on POST. Transfer-Encoding set to Chunked.
# Supplemental info (logs, images, videos)
C9 release doesn't seem to be backward compatible as none of my requests works. Is there some parameter to restore the previous behavior?
# Test environment (full version information)

We believe this to be a duplicate of #52682 which has a test case.
If your test case differs from it then please attach it to the bug report so we can make sure it's tested and integrated in our regression tests. Thanks!
