Default varnish configurable

[runelaenen]

The varnish container comes with some default configurations.

For example in 'defaults/vcl_recv.vcl' the following code blocks any XMLHttpRequests from being cached.

    # Do not cache ajax requests.
    if (req.http.X-Requested-With == "XMLHttpRequest") {
        set req.http.X-VC-Cacheable = "NO:Requested with: XMLHttpRequest";
        return(pass);
    }

Since this is executed before the 'lando.vcl', it seems like it is not possible to override this.

Do you think that there could be a way to override these defaults-files?
On the production server this is no issue, since I can just edit the files there. But in a container that's not really a possibility.

Hello,
I see that this issue was opened a few years ago, but I have the same need.
Is there a way to completely remove or at least override the default Varnish configuration that comes with the Varnish Lando service?

Pour info j'ai pu faire ce que je voulais avec les instructions suivante dans la config de Lando :

services:
  varnish:
    type: varnish
    scanner: false
    config:
       vcl: lando/varnish.vcl # will be renamed to /etc/varnish/lando.vcl by lando
    overrides:
      command: [
        "/usr/sbin/varnishd", "-F", "-a", ":80", "-f", "/etc/varnish/lando.vcl", # Force la prise en compte du fichier de configuration custom seul (sans les surcharges de config par défaut injectées par Lando) au démarrage du daemon de Varnish
        "-s", "malloc,256m", # stockage en RAM & limite de mémoire allouée au cache fixée à 256 Mo.
        "-S", "none" # pas de secret necessaire pour les commandes d'admin (varnishadm) comme pour la purge par ex
      ]
