That’s great. However, I’ve been testing with Varnish 3.0.3 running in CentOS 6.5, using a minimal VCL importing the example VMOD (https://github.com/varnish/libvmod-example) to generate a synthetic response using the example.hello() method. After changing the “Hello” string included in the VMOD by something else, recompiling and reinstalling the VMOD, the behaviour does not change when reloading the service. Only a restart of the service seems to work to update the VMOD. Maybe I’m missing something here. I’ll do some more testing using the CLI… Thanks, — Carlos Abalde.
