The MAC signature found in the HTTP request is not the same as the computed signature.

Question

I'm very simply retrieving a document by Id.

In an HttpGet (this is c# and MVC) i can get the document. In a PostBack where i get the document again i get this weird error.

I have no idea even where to start trying to hunt this one down, can any advise steps to debug here?

thanks,
Paul
