Shibboleth Developers

[<>]

Hi,

I'm tasked with shibbolizing a ASP.NET application. I just have a sanity check
question.

I think I grasp the basic concept, and am plumping for my Application doing
the Session handling, authenticating users by matching specified Header
variables (provided by Shibboleth authenticated users) with our mathing DB
values.

My question is this:

Once a user is authenticated by Shibboleth are the specified Header variables
sent with every subsequent HTTP request there on in? Or are the only provided
once at entry point?

Thanks,

Steve
