Configuration parameters

The URLFETCH function sends HTTP(S) GET requests, waits for the responses and puts them on the stack.

For security reasons, the stack must be authenticated for this function to work, see AUTHENTICATE.

Since 2.7.0, this function also accepts a MAP of headers.

URLFETCH is available since version 1.0.2.
