Asynchronous callback

Thanks Bechir,

 

Looking forward to your reply. :-)

You want to know what's happening under the hood, OK I will answer you as soon as possible about this issue

Thanks Bechir,

 

The article is nice about how to deal with web services in an asynchronous way. But my question is not how to use web services in an asynchronous way, but what underlying technologies is used when we got the asynchronous result.

Let me quote here again. Any ideas? :-)

--------------------
My question is, how will the result be delivered to client?

- Does the proxy on client side opens a port and listen to the return SOAP message containing the result?

- Does the client use keep alive technique and keeps the Http connection open/live from the beginning (when we call BeginXXX to invoke the web services) to the end (when the result is ready) -- if implemented in this way, there is no need for the client to open a port to listen?

- Or implemented in some other ways?
--------------------

thanks in advance,
George

I guess this article fits your requirement, and this is another article about the same issue, it is more clear but the code is written in VB anyway the important is the explanation

Thanks Bechir,

 

I have read throught the document you referred. It is about asynchronous operation in Media Foundation. But my question is about how asynchronous is implemented in web services specific technologies. Could you read my original post again and if I am wrong to find the relationship between the document you referred and my question, please feel free to correct me. :-)
