public string RequestCommand { get; set; }

The set of commands that are considered valid for a particular request depends on the protocol used to talk to the remote service. For an HTTP request any valid HTTP method—such as

PUT

,

GET

,

POST

and

DELETE

—will do. Other protocols might have their own set of commands; for example, FTP has

LIST

while WebDAV supports

COPY

. Note that specifying the command using this option will simply set the word in the request and won't change curl's behavior in any way. If curl already has a dedicated option to perform a particular operation, it's almost always better to use that option instead of specifying the command directly, since that will make sure that curl behaves accordingly. For example, in order to send an HTTP

HEAD

request, setting the

"HEAD"

command in the request isn't enough. In that case, the dedicated

-I --head

option is a far better choice.
