Hi, I am using the "Emiller's Guide To Nginx Module Development", in section "3.1.4. Sending the body", there is allocation to: ngx_chain_t out. I do not understand where is the free for this allocation? Should it be a handler which free the buf? Thanks, Ortal Levi Posted at Nginx Forum: https://forum.nginx.org/read.php?2,263346,263346#msg-263346
