Ext.Connection wraps the functionality of the YAHOO code.

and where can i get the correct syntax how to call Ext.Connect???

HttpProxy calls Connect to make a web request. Or, look at the source for Connect - it's pretty simple.

Hmm, but then Ext.data.Connection.request(..) doesnt work. Should i instantiate this class first before using it? Then the yahoo.util.connect.asyncrequest is one line shorter ?

I'm using Ext.lib.Ajax.request() to make asynchronous Ajax requests.

var success = function (o)
// Success callback
// o is an instance of XMLHTTPRequest

var failure = function (o)
// Failure callback

var url = 'someurl.php';
var params = {
'param1': 'value1',
'param2': 'value2',
'paramN': 'valueN'
params = Ext.urlEncode(params);

Ext.lib.Ajax.request('POST', url, {success: success, failure: failure}, params);

Hope this helps.

Yeps thats the same as calling the YAHOO.util.Connect.asyncrequest directly and does not involve a Ext.Connection object. Hence my intercepting of the handleresponse of the connection object has no result in that case. So then still the best way is to instantiate my own connection object and use that for async requests? (if i want to be able to intercept all requests?)

Yes. Look at how HttpProxy creates a new Connection object. You should be able to trace thru this entire process by looking at any example that creates a Store object and the associated HttpProxy.
