Summary

Parameters
$uri The URI of the document whose response header is being requested.

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:http-head("http://www.my.com/document.xhtml",
     <options xmlns="xdmp:http">
       <authentication method="basic">
         <username>myname</username>
         <password>mypassword</password>
       </authentication>
     </options>)
=> the response header from the server
