Avoid causing libcurl to use chunked Transfer-Encoding for POST bodies #155

Open mbaynton opened 2 years ago

mbaynton commented 2 years ago

For #154 I had success by preventing the recorder proxy from employing chunked Transfer-Encoding. It seemed like connect et. al just don't do well when given properly formed chunked requests.

Here's someone driving libcurl with PHP who had a similar issue: https://github.com/php/php-src/issues/8165 Based on the age of that, I wonder if cURL going to chunked Transfer-Encoding when it is uploading from CURLOPT_READFUNCTION and the length hasn't been provided ahead of time is a newer behavior.

Disclaimer: I don't really write much R :upside_down_face:
