WSE 1.0, InputFilter, SoapContext

[oliver.wulff]

Hi all

An InputFilter is called either when a soap request arrives in ASP.NET or
when the soap response arrives at the client. How can I figure out in the
input filter whether it's an incoming request or an outgoing response?
Anyway, when should I use the soap request context and when the soap
response context?

Thanks for your help
Oliver
