http := TChilkatHttp.Create(Self);

// The PROPFIND request to be sent will look similar to this:
// This is from RFC 4918 at http://tools.ietf.org/html/rfc4918#section-9.1.3

//      PROPFIND /file HTTP/1.1
//      Host: www.example.com
//      Content-type: application/xml; charset="utf-8"
//      Content-Length: xxxx
// 
//      <?xml version="1.0" encoding="utf-8" ?>
//      <D:propfind xmlns:D="DAV:">
//        <D:prop xmlns:R="http://ns.example.com/boxschema/">
//          <R:bigbox/>
//          <R:author/>
//          <R:DingALing/>
//          <R:Random/>
//        </D:prop>
//      </D:propfind>

// Build the HTTP request object. 

// The HTTP verb should be "PROPFIND"
req.HttpVerb := 'PROPFIND';

// The Content-Type should be "application/xml", and
// the charset attribute in the Content-Type header should
// be utf-8:
req.ContentType := 'application/xml';
req.Charset := 'utf-8';
req.SendCharset := 1;

// Load the request body with the XML.  Your application 
// is free to construct the XML using any means desired.
// Once the XML is prepared, load it into the request body
// like this:
xmlBody := 'This is the string that should contain the XML body...';
success := req.LoadBodyFromString(xmlBody,'utf-8');
if (success <> 1) then
  begin
    Memo1.Lines.Add(req.LastErrorText);
    Exit;
  end;

// For this example, pretend the WEBDAV endpoint is:
// https://webdav.chilkatstorage.com/

// Note: There is no actual "chilkatstorage.com" site.  
// This is only an example...

// The "path" part of this endpoint URL is simply "/".

// Send the request to the WebDAV endpoint using 
// the SynchronousRequest method:

resp := http.SynchronousRequest('webdav.chilkatstorage.com',443,1,req.ControlInterface);
if (http.LastMethodSuccess = 0) then
  begin
    Memo1.Lines.Add(http.LastErrorText);
    Exit;
  end;

// Get the XML response:

responseXml := resp.BodyStr;
Memo1.Lines.Add('XML Response: ' + responseXml);

// Get the response status code, such as 207

statusCode := resp.StatusCode;
Memo1.Lines.Add('StatusCode = ' + IntToStr(statusCode));
end;
