Could you help me in confirming the default behavior of vcl_recv in Varnish ?
vcl_recv definition that comes in default.vcl file is commented out in the application setup.
We have provided our custom version of vcl_recv in a vcl file without specifying a return(lookup) or lookup statement. However caching seems to be proper when trying to access an images or static content. Does varnish internally implement some sort of logic to cache on top of what is defined in default.vcl's vcl_recv and user defined vcl_recv ?
Thanks
