varnish regex or for if (bereq.url ~ "

Question

I try to create a regex for varnish cache v4

sub vcl_backend_response {


 if (bereq.url ~ "(/media|/bundles|/sonata_admin/|/build)$" ) {

{
        unset beresp.http.set-cookie;
        set beresp.http.cache-control = "public, max-age=2592000";
        set beresp.ttl = 30d;
        return (deliver);
    }

also I try

 if (bereq.url ~ "(\/media|\/bundles|\/sonata_admin|\/build)$" ) {

I want to include all files where location starts from /media or /bundles or ...

this not work

Answer 1

In your config, it doesn't work because you're matching up with $ that stands for "at the end of string".

You want to use ^ which is "match at the beginning", thus:

if (bereq.url ~ "^/(media|bundles|sonata_admin|build)") {
    unset beresp.http.set-cookie;
    set beresp.http.cache-control = "public, max-age=2592000";
    set beresp.ttl = 30d;
    return (deliver);
}
