WWW+WWWForm 500 Internal Server Error

Unity Engine
1

I am trying to send data to a webserver via WWWForm but I get this error. Looking into apache logs, I can see unity accessing the requested page but there is no error in logs. The server side code is ok, I’ve tested it with a GET from unity and is doing what is suppose to do. But when I switch to sending data with wwwform via POST I get “500 Internal Server Error” no matter what i do.

Using GET like this WWW www = new WWW(url + “?field1=”+value1+“&field2=value”+“&field3=”+value3); works as intended without any error.

Here is a test I’ve done outside of my game:

using UnityEngine;
using System.Collections;

public class senddata : MonoBehaviour
{
	private bool once = false;
	WWW www = null;

    void OnGUI()
    {
        if (GUI.Button(new Rect(Screen.width / 2 - 100, Screen.height / 2 - 20, 200, 40), "Send"))
		{	
			StartCoroutine("Send");
        }


    }

	IEnumerator Send()
	{
		WWWForm form = new WWWForm();
		form.AddField("f1", "value 1", System.Text.Encoding.UTF8);
		form.AddField("f2", "value 2", System.Text.Encoding.UTF8);
		form.AddField("f3", "value 3", System.Text.Encoding.UTF8);
		www = new WWW("obscured", form);

		yield return www;

		if(!string.IsNullOrEmpty(www.text)  !once)
		{
			Debug.Log(www.text);
			once = true;
		}
	}
}

Hello,

Check the crossdomain.xml

The file is in place and the client is for windows desktop.

Problem solved, I use Codeigniter framework on the server side and this had the Cross Site Request Forgery and Global XSS Filtering on. Disabling them removed my problem.
