原文摘录

摘自原文(1601 字符中的一小部分)
Summary: Curl doesn't consider IPv6 address zone index when doing connection reuse. if connection exists to specific IPv6 address (and other conditions for connection reuse are fulfilled) it will be reused for connections regardless of the zone index.
原文中的代码
Listening on :: 9999
Connection received on somehost someport
GET /x HTTP/1.1
Host: [ipv6addr]:9999
User-Agent: curl/7.83.0-DEV
Accept: */*

GET /y HTTP/1.1
Host: [ipv6addr]:9999
User-Agent: curl/7.83.0-DEV
Accept: */*
