Nginx + embedded perl, sharing variables across workers

[yuri]

Hi,

I have written a perl handler that generates a random value and needs to
maintain the same value consistently across all other perl handlers (as
there is 1 perl handler per nginx worker) until the workers are
restarted;

I've attempted to do so by issuing $r->variable('varname', $rand) to no
avail - is it impossible to set a variable defined in nginx.conf and
have the new setting affect any further reads of that variable from
other workers?
Which options do I have if I'd like to share $varname across multiple
perl handlers?

Thanks!
Yuri
