HoneyryderChuck	afbde420a7	proxy: fix incorrect connection #send definition never calling super this made several plugins unusable with the proxy plugin, because a lot of them are dependent on Connection#send being called and overwritten. This was done so to avoid piping requests when intermediate connect-level parsers are in place. So in the way, when the conn is initial, original send is closed; when not, which should almost never happen, a second list is created, which is then piped when the connection is established, back to original send.	2023-06-26 16:45:27 +01:00
