- spiffy-user #!optional name-or-uidparameter
The name or UID of a user to switch to just after binding the port. This only works if you start Spiffy as root, so it can bind port 80 and then drop privileges. If #f, no switch will occur. Defaults to #f.
If you set this to non-#f, you'll need to install the posix-groups egg, otherwise a runtime exception is raised.
