In one of my Graphing programs written in Java, I am trying to send a

I found some code on internet that helped me post text data to the
module.

Can someone suggest how I may post the graphics image binary data using
POST method

URL url = new URL("http://www.your-server.com";); HttpURLConnection
connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.connect();
DataOutputStream out =
new DataOutputStream(connection.getOutputStream()); // use one of write
methods of out
out.flush();
out.close();

I'm actually in the process of doing this right now. I'm going to be posting the image to a URL that is a PHP script. When I was looking at this I thought that this really made more sense to use a PUT method to post the image, but the guy working on the PHP side insisted on using a POST method.

Is there a reason that POST would be selected over PUT for this application? Are there reasons to go with PUT here?

Thanks.

If you are sending other data with the request(i.e. a caption for the picture), POST is the designed protocol. If you are just sending a file to be saved to the server use PUT or POST. In other words POST is designed to put but PUT isn't meant to post. It's a distinction without a difference from your side of the code - if the PHP guy want's POST ...
