When the Shibboleth IdP redirects a browser back to the SP, it does it via a form that is auto-submitted (if javascript is enabled). The default form is very basic, so I decided to spruce up the page for idp-dev.

The original IdP.jsp page source is in this attachment, and the updated version is in this one.

You should also update the other JSP files (IdPError.jsp, IdPErrorBlameSP.jsp and IdPStale.jsp).

To see the new page, just log in to this blog.
