Hello, Our current implementation of Proxy is very tightly coupled to HTTP 1.0/1.1 protocol and not made to be easily extended. What do you think of switching to LittleProxy - https://github.com/adamfisk/LittleProxy Which has by the way started some work on HTTP/2 support: - https://github.com/adamfisk/LittleProxy/issues/229
This issue has been migrated to GitHub: https://github.com/apache/jmeter/issues/4319
