Dirty hack to make every request independent.

So far we could always have influenced the next request
by setting request headers *after* having made a request
(that is, by providing a "Given the HTTP request header *blah*"
*after* a "When I go to ...").

Note that such "Given"s should come *BEFORE* "When I go..."

Also, the way to achieve that violates every possible
programming commandment on earth.
