Hi.

In two words, I'm building .Net Client that will use WebServices to upload large amount of data. Client should inform user about upload and download progress. I've created SOAP extension to wrap WebService stream in chain. Similar to Using SOAP Extensions to provide progress notification for Web Service calls[^]

Download progress informer works perfect, but with upload I've one issue. On Response to WebService, original stream is wrapped by SoapExtensionStream and I can't get to original WebService stream to wrap it with my proress informer extension.

In other words in the method

override Stream ChainStream(Stream stream)

I need to get original WebService stream during Response to WebService, else it is not possible to get any info about upload progress..

Any ideas how I can do it?

Thanks in advance, Alexey
