Demonstrates how to send a WebDAV PROPFIND HTTP request. DataFlex

Use ChilkatAx-win32.pkg

Procedure Test
    Boolean iSuccess
    Variant vReq
    Handle hoReq
    Handle hoHttp
    String sXmlBody
    Variant vResp
    Handle hoResp
    String sResponseXml
    Integer iStatusCode
    String sTemp1

    Move False To iSuccess

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

    Get Create (RefClass(cComChilkatHttpRequest)) To hoReq
    If (Not(IsComObjectCreated(hoReq))) Begin

        Send CreateComObject of hoHttp
    End

    // 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/">

    // Build the HTTP request object. 

    // The HTTP verb should be "PROPFIND"
    Set ComHttpVerb Of hoReq To "PROPFIND"

    // The Content-Type should be "application/xml", and
    // the charset attribute in the Content-Type header should
    // be utf-8:
    Set ComContentType Of hoReq To "application/xml"
    Set ComCharset Of hoReq To "utf-8"
    Set ComSendCharset Of hoReq To 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:
    Move "This is the string that should contain the XML body..." To sXmlBody
    Get ComLoadBodyFromString Of hoReq sXmlBody "utf-8" To iSuccess
    If (iSuccess = False) Begin
        Get ComLastErrorText Of hoReq To sTemp1

    // 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:

        Showln sTemp1

    // Get the response status code, such as 207
