Unfortunatelly the old (or current ;-) request api doesn't handle all
headers unsetting. If I remember well, I think in that case, if you
set it to -1 it will be unset. Otherwise, feel free to hack the
request API to match your needs, the new one will provide the
appropriate unsetters (in the upcoming release, setting the value to
-1 is the way to do that).

Again, feel free to hack the old request API. The next release will
allow you to:

setHeaderValue(<header-access-token>, null);

to unset any header value.
