How do I get the req.url in vcl_backend_response?

My configs are based on Varnish 3.0 and I have been updating them. But I ran into a snag. `vcl_fetch` was replace to `vcl_backend_response`. Inside of `vcl_fetch` you used to be able to use `req.url` but not anymore inside of `vcl_backend_response`. So I am left with three `if` statements that won't work: ``` sub vcl_backend_response { set beresp.do_esi = true; if (!(req.url ~ "wp-(login|admin)")) { unset beresp.http.set-cookie; } if ( req.http.host ~ "[0-9]\.example\.com" || req.http.host ~ "[0-9]\.example\.com") { set beresp.ttl = 60s; } if ( req.url ~ "\.(html|htm|css|js|txt|xml|svg)(\?[a-z0-9=]+)?$" ) { set beresp.do_gzip = true; } } ``` How do I convert these configs in Varnish version 4.0? By the way I am new to Varnish VCL.
