This function's implementation is taken directly from Beaker,

with HTTPS detection added. When accessed over HTTPS, force

setting cookie's secure flag.

The only difference from that original code is that we switch
|
|
|
the secure option on and off depending on the URL scheme (first

two lines). To avoid concurrency issues, we use a local options

variable.
