Shibboleth SP Server variables in IIS

I have confirmed that the only way to see the attributes in classic asp is by
turning on useHeaders or by the ill-advised attributePrefix="HTTP_"
I have also confirmed the attributes show up in Request.Headers in
so they are indeed header values.

However in with useHeaders false and useVariables true,
Request.ServerVariables[] does not return any "Shib" or IdP attribute
variables on my server, I tried turning off as much as I could while still
having a running website, but no luck.

Maybe it's specific to our app, or server, I don't know but for reference
our setup is:
Windows 2012R2 64 bit / IIS 8.5
App Pool:
.NET CLR: 4.0
Enable 32bit: true
Managed pipeline: classic
