Okay I'm doing a simple post like
WebClient webClient = new WebClient();
webClient.Headers["content-type"] = "application/x-www-form-urlencoded";
webClient.Encoding = Encoding.UTF8;
webClient.UploadStringAsync(new Uri(ResultServerAddress, UriKind.Absolute), "POST", "data=" + "stuff");
When I deploy this to dev, and look at the post in fiddler, I see a 404 error with the address of the page I'm posting to looking for crossdomain.xml. Is there no way I can tell my code to not look for this file? Or does every site that wants to revieve posts from mine have to have a crossdomain.xml file in place?
