title: How to send GET request without any parameter in EXT-JS
body: <p>In <em>Java script</em> when we send GET request it goes without adding any parameter, But in <em>EXT-JS</em> it auto add CallBack parameter. (i checked with Wireshark &amp; firebug)</p>
  
  <p>we are able to see xml on browser on Juniper MFC  URL, because it sends GET request, but browser show 404 error when <em>REQUEST</em> sent with any parameter like 'callback parameter' <em>(acc to Firebug, browser &amp; wireshark)</em>.</p>
  
  <p>So i need to create a new proxy Extend from <em>ScriptTagProxy,</em> in that modified load function.
  Please tell me how i can do that.</p>
  
  <p>I have done the following but no luck. </p>
  
  <pre><code>        var _Proxy = Ext.extend(Ext.data.MyScriptTagProxy({
           url: 'http://IP:PORT/App',
           method: 'GET',
           nocache: false,
           restful: true 
           }); 
  
   Ext.define('Ext.data.MyScriptTagProxy' {   
   extend: 'Ext.data.ScriptTagProxy',
   constructor:function(cnfg){
   this.callParent(arguments);//Calling the parent class constructor
        this.initConfig(cnfg);//Initializing the component
        this.on('beforerender',this.beforeRender);
   }});
  </code></pre>
  
  <p>IF there is another solution for topic also please suggest.</p>
