Calling a API

[txandy]

Hello!
I'm starting with zimlets, and i have problems

i'm making a zimlet, this zimlet call a API, with this method,

http://randomurl.com/user_sistem?user=MYUSER&pass=MYPASS

This url return me a file XML with de ID of my account.

I'm using this example for de wiki, but i modify for direct acces, non proxy

com_zimbra_example_httpgetpost_HandlerObject.prototype._executeExternalHttpGet = 
function() {
    var url = "http://randomurl.com/user_sistem?";
    var param ="user=MYUSER&pass=MYPASS";
    var to= url+param;
    // submit the URL and asynchronous response (using callback)
    AjxRpc.invoke(null, to, null, new AjxCallback(this, this._httpExternalGetCallback), false);
   
};
     com_zimbra_example_httpgetpost_HandlerObject._executeExternalHttpGet
com_zimbra_example_httpgetpost_HandlerObject.prototype._httpExternalGetCallback =
function(response) {
    if (response.success == false) {
        // display the error response
        appCtxt.getAppController().setStatusMsg("Error: " + response.text, ZmStatusView.LEVEL_WARNING);
        return;
    }
    // display the response
    appCtxt.getAppController().setStatusMsg(response.text);        

};

When i call for this, firebug send my GETMINICALLREQUEST : Aborted X

This is de best method to do this? Another method?

Thx
