Head method:
Head request is just like a get request, except it asks the server to return the response headers only, and not the actual resource (ie: no message body).
This is useful to check characteristics of a resource without actually downloading it, thus saving bandwidth.
Use head when you don't actually need a file's contents.
The response to a head request must never contain a message body, just the status line and headers.
