Since you know .NET then you could handle this with a HttpWebRequest in a DLL and expose it as a COM object to VFP ?

Update: The first code snippet here is pretty much it : http://msdn.microsoft.com/en-us/magazine/ee309509.aspx

>Hi,
>
>I have been asked to use a restful API (I believe that's what it's called to retrieve and post files to a folder on the web - or in the cloud as is the common term now).
>
>How do I do this from VFP?
>
>I have been given the following information:
>
>Viewing:
>
>To view a document simply go to the following URL. It will output a pdf file.
>
>http://***.***.***.***/api/index.php/documents/index/
>
>Example of a live document:
>
>http://***.***.***.***/api/index.php/documents/index/8CF8797D-4FDF-7A4C-3750-4C8BFF1A4BC4
>
>Uploading:
>
>To upload a file you have to do a HTTP POST to this URL:
>
>http://***.***.***.***/api/index.php/claims/upload
>
>It expects 2 parameters:
>
>doc_pk - the primary key for the field in the ClaimDocuments table which holds the description etc on the document
>pdf - this should be a base64 encoded string of the contents of the file to upload
>
>This is a sample of the code I use to upload a document:
>
>$response = $this->rest->post('claims/upload', array(
>'doc_pk'=> $doc_pk,
>'pdf' => base64_encode(file_get_contents('resources/img/doctors.jpg'))
>), 'json');
>
>As you can see I first read the contents of the file, then encode it, then send it to the RESTful server.
>
>The server will return a response in JSON. This is the php dump of that response:
>
>stdClass Object
>(
>[error] => false
>[message] => File uploaded successfully.
>)
>
>The error variable will be true or false. The message will correspond to the error state.
>
>To force an error you can POST to the URL with no variables.
