如何在 Varnish 中创建 default.vcl 中的自定义函数？
How to create custom function in default.vcl within Varnish?
我的 vcl 中有重复代码，我想创建自定义函数而不嵌入内联 C 代码。可能吗？
您可以像这样定义自定义子例程
sub my_subroutine {
...
}
并这样称呼它：
call my_subroutine;

Subroutines in VCL take neither arguments nor return values. Each
subroutine terminates by calling return (action), where action is a
keyword that indicates the desired outcome. Subroutines may inspect
and manipulate HTTP header fields and various other aspects of each
request. Subroutines instruct how requests are handled.
Subroutine example:
sub pipe_if_local { if (client.ip ~ local) {
return (pipe); } }
To call a subroutine, use the call keyword followed by the
subroutine’s name:
call pipe_if_local;
Varnish has built-in subroutines that are hook into the Varnish
workflow. These built-in subroutines are all named vcl_*. Your own
subroutines cannot start their name with vcl_.
