Fetch the data through Varnish

GET -Used http://localhost:80/

HEAD and GET are the same lwp-request tool.
HEAD replies with HTTP headers, while GET returns everything.

In this case:
-U prints the request headers
-s prints the response status code which usually is “200 OK” or “404 File not found”
-e prints the response headers
-d doesn’t display the content of the response.
