MyWrappingServlet
{
doPost(req, res)
{
// ...
URL uploadUrl = new
URL(blobstoreService.createUploadUrl("successPath"));
copyRequestDataToUrl(req, url);
res.getOutputStream().print("."); // the magic character
}
// this method applies the request data and headers to given URL
copyRequestDataToUrl(req, url)
{
// ...
}
}
