HttpWebRequest - how to measure traffic

[ilya2]

Hi,

 

I'm working on a chat application which uses HttpWebRequest/Response to communicate with a web service.

 

Now I would like to add a feature that informs user about the actual (and accurate ;) number of bytes that have been sent/received so far.

 

Do you have any idea about how to do this?

I haven't found any way to intercept the HttpWebRequest/Response streams which would include any headers received or sent.

 

Thanks a lot for your suggestions!
