// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

req := CkHttpRequest_Create();
http := CkHttp_Create();

// 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"
CkHttpRequest_putHttpVerb(req,'PROPFIND');

// The Content-Type should be "application/xml", and
// the charset attribute in the Content-Type header should
// be utf-8:
CkHttpRequest_putContentType(req,'application/xml');
CkHttpRequest_putCharset(req,'utf-8');
CkHttpRequest_putSendCharset(req,True);

// 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 := CkHttpRequest_LoadBodyFromString(req,xmlBody,'utf-8');
if (success = False) then
  begin
    Memo1.Lines.Add(CkHttpRequest__lastErrorText(req));
    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 HttpSReq method:

resp := CkHttpResponse_Create();
success := CkHttp_HttpSReq(http,'webdav.chilkatstorage.com',443,True,req,resp);
if (success = False) then
  begin
    Memo1.Lines.Add(CkHttp__lastErrorText(http));
    Exit;
  end;

// Get the XML response:

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

// Get the response status code, such as 207

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

CkHttpRequest_Dispose(req);
CkHttp_Dispose(http);
CkHttpResponse_Dispose(resp);
