How to handle status other than 'Success' gracefully

[HDenBreejen]

My IDP responds with a 'Responder' status when the user at some point cancels the authentication.
SAML2 throws an exception when on any status other then Success.

I need to handle this situation gracefully in my app. Perhaps I would like to redirect to a 'Try again' page.
The only way of doing this I can think of, is examining the exception. A Saml20Exception, however, does not have a error code, so I would have to resort to testing the Mesage property.

Unless there is a better way to approach this situation, I would suggest adding some properties to the Saml20Exception, so the application can handle specific situations.

Specifically for my scenario, an extra endpoint attribute for a non-success redirect-url would do fine, but that would not be as versatile.

I would instead say that a more robust list of Exceptions would be better here for you to catch. Do you just need it to throw something like a Saml20BadStatusCodeResponse or something?

Sorry for the delayed response - I had some time off line..
Introducing a set of specific exceptions would be fine too. That would give the application the opportunity to differentiate where necessary.
For my exact situation, a Saml20BadStatusCodeResponse exception, having a property with the actual statuscode received, would be great.
