Basic usage involves passing a url and getting a response and data back:

http-get ( url -- response data )

Utilities to retrieve a url and save the contents to a file:

download ( url -- )

download-to ( url file -- )

Advanced usage involves constructing a request, which allows HTTP cookies and HTTP headers to be set:

<get-request> ( url -- request )

http-request ( request -- response data )

The http-get and http-request words output sequences. This is undesirable if the response data may be large. Another pair of words take a quotation instead, and pass the quotation chunks of data incrementally:

with-http-get ( url quot -- response )

with-http-request ( request quot -- response )
