Cancel remoteobject transaction

Question

Hello,
I'm wondering if it's possible to cancel a remotobject's transaction.
This is the case:
A user may upload articles to my backend database. But while this is uploading it must be possible to disconnect this transaction. (If the transaction takes too long for example it must be possible to cancel this).
I did some research but couldn't find it yet.
Here's some code.
My delegator:
            var token:AsyncToken=this.service.saveArticle(articleVO);
            token.resultHandler=responder.result;
            token.faultHandler=responder.fault;
            token.addResponder(responder);
My Service:
                var channel:AMFChannel=new AMFChannel("my-amf", "http://localhost:8080/.../messagebroker/amf");
                var channelSet:ChannelSet=new ChannelSet();
                channelSet.addChannel(channel);
                articleService.channelSet=channelSet;
         <mx:RemoteObject id="articleService"               
                     destination="articleService"/>
I think there are different solutions. Call the remoteobject's disconnect function, the channelset's disconnect function or something with the asynctoken. But I didn't figure it out yet. Can someone help me plz?
thx

BlueVeinz, Michael and all,
I wonder if this is in fact always possible? Presumably Flex can only cancel the things over which it has control, not the detailed behaviour of remote systems. For example, a database engine may grant you permission to query but not cancel. The documentation that Michael pointed to says (among other things) under the cancel() entry "Cancels the last service invocation or an invokation with the specified ID.       Even though the network operation may still continue, no result or fault event       is dispatched" - in other words Flex will stop nagging you about it, but it may well not be possible to do anything about the operation itself. Again, one can imagine a remote web service operation that simply exposes no faciilty for being cancelled - the best you can do is to flag your lack of interest in it.
From a user's perspective this may well be enough, but if the original question related to actual resources being used I think the issue is different.
All the best,
Richard
