Difference Between HEAD, GET , POST
HEAD
Asks for the response identical to the one that would
correspond to a GET request, but without the response body.
This is useful for retrieving meta-information written in
response headers, without having to transport the entire
content.
GET
Requests a representation of the specified resource.
Note that GET should not be used for operations that cause
side-effects, such as using it for taking actions in web
applications.
POST
Submits data to be processed (HTML form) to the
identified resource (server side data). The data is included
in the body of the request. This may result in the creation
of a new resource or the updates of existing resources or both.
