.NET Forum / ASP.NET / Web Services / December 2004HttpModule not able to access SoapEnvelope
Hi all, I want to ensure that my wSE 2.0 web service is being called with at least one security token. I have a function that validates that using the RequestContext.Security.Tokens collection. Instead of calling that function from every Soap Method, I want to put this in an HttpModule. While I haven't actually tried it yet, I believe this will work just fine. I can get to the request's SoapContext object. However, for future plans, I would also want access to the SoapEnvelope for that request. I have tried hooking into three events: AUthenticateRequest, BeginRequest, and PreRequestHandlerExecute. In all of these events, the Envelope property of my SoapContext is Nothing (null). Is there a way I can access the Envelope in an HttpModule? Thanks, --- Sven. > I want to ensure that my wSE 2.0 web service is being called with at > least one security token.

I suggest to implement a filter (input or output or both) which contains all information (security, addressing, etc). But probaly you have to do something else ?

The customer will have the ability to add policy using policy files. But the minimum requirement will always be that there should be at least one SecurityToken. > > However, for future plans, I would also want access to the > > SoapEnvelope for that request.

I am sure I am passing a security token, because if I put the check in a web method, it works. Signature--- Sven. > Hi all, > [quoted text clipped - 20 lines] > > Sven. Hi, yes, this also makes sense. In the HTTP module, no SOAP processing has happened yet. The SoapContext stuff is filled in for you AFTER the stage in the ASP pipeline where the HTTP module gets control. If you want to get access to the payload data from the HTTP module, you need to crack the input stream yourself.

In an HTTP module you have access to the request stream - and this contains an HTTP request, which in turn contains an HTTP header and then a SOAP request. You have to find the envelope yourself - since it hasn't been pulled apart by the ASP.net stack yet.
