Can't form a simple POST or GET http request. No data returns.

Hi,
I'm having problems forming an http request in java.
Here's what I do:

I've got a simple php (java.php) file on my apache server, here's it's code:

Code :

---

<?php
	$post_var = $_POST['post_var'];
	if (!isset($post_var)) $post_var = $_GET['post_var'];
	if ($post_var == 1) echo "works";
	else echo $post_var . ": post_var";
?>

---

If I do this request:

Code :

---

http://warfarex.com/java.php?post_var=1

---

from browser, I get "works" output. The same if I send POST or GET request from a ActionScript 3 client.
But Java keeps on giving me this:

Quote:

---

: post_var

---

So, as you can see, it's the output of an "else" block.

And finally, here is the Java code I use to make these requests:

Code java:

---

String request = "?post_var=1";
URL url = new URL("http://warfarex.com/java.php");
URLConnection connection = url.openConnection();
connection.setDoOutput(true);
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(connection.getOutputStream());
outputStreamWriter.write(request);
outputStreamWriter.flush();
System.out.println(request);
 
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String response;
while ((response = bufferedReader.readLine()) != null) {
	System.out.println(response);
}
outputStreamWriter.close();
bufferedReader.close();

---

What's wrong with this code?

regards, Konstantin.

I've just found the problem myself.
It was the question mark in my request string.
This request:

Code :

---

String request = "post_var=1";

---

will work as a charm
