Headers are subject to spoofing attempts by the client and despite the many
pains the SP takes to prevent that, it's never going to be provably immune
to new ways of attacking it that might get around the protections,
particularly when there are bugs in the web server itself.

I welcome and encourage attempts to hack it, and believe it's quite
protected provided all the IIS caveats are observed, but environment
variables are always protected.
