I was goofing around with some of the examples I've seen floating around the Internet on various ways to upload files to a remote web server using the HTTP POST method. The reason being that I've seen a lot of questions on the ASP.NET board lately about not being able to get it to work correctly. So, I thought I'd add my 2 cents worth in the documentation ring to (hopefully) provide some additional documentation.

#1. Although it doesn't state it verbatim, to use HTTP POST you have to have a receptor running on the remote web server. This can be a web server, ASPX file, or whatever. Just something to accept an HTTP POST. Just sending an HTTP POST to a web directory will not automatically upload a file for you (a common misconception).

#2. If you're going to use the WebClient.UploadFile, then remember to include the fully qualified directory and filename. Even if you intend on using default.aspx as your receptor's name, the following won't work:

httpResponseArray = _
myWebClient.UploadFile("http://servername.com/dir/", "POST", "LocalFileName")

You'll need to use the fully qualified directory and filename for UploadFile() to work:

httpResponseArray = _
myWebClient.UploadFile("http://servername.com/dir/default.aspx", "POST", "LocalFileName")

Hope this helps those who are looking for help uploading files with HTTP in VB.NET (or any other managed language - VB.NET just happens to be my preference lately).
