   [options as Object?]

Summary

Usage Notes

The http functions only operate on URIs that use the http or https schemes; specifying a URI that does not begin with http:// or https:// throws an exception.

If an http function times out, it throws a socket received exception (SVC-SOCRECV).

Example

xdmp.httpHead("http://www.my.com/document.xhtml",
     {
       "authentication" : {
         "method" : "basic",
         "username" : "myname",
         "password" : "mypassword"
       }
     })
=> the response header from the server
