apache - Varnish not ignoring subdomain despite vcl rules -

i running basic lamp server apache on port 80, , varnish on port 81. attempting exclude subdomain of primary site entirely, have had no luck in doing far, , i'm not sure why.

as can see below, have rule in place a) skip logged in users on subdomain, , b) skip subdomain entirely. neither of these seem work however. there wrong vcl configuration?

backend default { .host = "my.server.ip.address"; .port = "80"; }    sub vcl_recv { call identify_device;      # allow back-end serve stale content if responding slowly.     set req.grace = 2m;      # cache following file types users.     if ( req.url ~ "(?i)\.(png|gif|jpeg|jpg|ico|swf|css|js|html|htm)(\?[a-z0-9]+)?$" ) {             unset req.http.cookie;     }      # don't serve cached pages logged in users     if ( req.http.cookie ~ "wordpress_logged_in" || req.url ~ "vaultpress=true" ) {             return( pass );     }      #lets skip logged in users on subdomain too!     if ( req.http.cookie ~ "dmr_user" ) {     return (pass);     }      #skip subdomain.domain.com     if (req.http.host ~ "subdomain.domain.com") {     return (pass);     }      #following woocommerce , comments     if (req.url ~ "^/(cart|my-account|checkout|addons|wp-comments-post)") {     return (pass);     }      #lets skip logged in users on entries too!     if ( req.http.cookie ~ "dmr_user" ) {     return (pass);     }      if ( req.url ~ "\?add-to-cart=" ) {      return (pass);      }      # drop cookies sent wordpress.     if ( ! ( req.url ~ "wp-(login|admin)" ) ) {             unset req.http.cookie;     }          }  sub vcl_fetch {   if (beresp.ttl < 180s) { set beresp.ttl = 180s; }     if (!(req.url ~ "wp-(login|admin)")) {             unset beresp.http.set-cookie;     }  }  sub vcl_hash {     hash_data(req.http.x-device); }   sub vcl_deliver {     if (obj.hits > 0) {             set resp.http.x-cache = "hit";     } else {             set resp.http.x-cache = "miss";     }  } 

you skipping processing of subdomain halfway handling, ie instructions executed in order. moving skip domain check directly @ top of sub vcl_recv should ensure no other rules gets executed against requests subdomain.
