I think (and hope) I found a solution. In my apache configuration, I removed PerlSetEnv for the cookie settings and now embperl consistently configures the cookie as configured.
I changed *PerlSetEnv EMBPERL_COOKIE_PATH /* to *EMBPERL_COOKIE_PATH /* Although, the embperl log still shows requests being made without the embperl environment variables. For example, [6410]REQ: ***** Start Request at Thu Apr 5 12:23:57 2018 [6410]Use App: Expatriates [6410]ENV: MOD_PERL_API_VERSION=2 [6410]ENV: MOD_PERL=mod_perl/2.0.4 [6410]Using APACHE for output... Other requests show the environment variables. [6410]REQ: ***** Start Request at Thu Apr 5 12:23:36 2018 [6410]Use App: Expatriates [6410]ENV: EMBPERL_MAIL_ERRORS_TO=jta...@gmail.com [6410]ENV: EMBPERL_MAILDEBUG=0 [6410]ENV: EXPATLIB=/opt/expatriates.com/lib [6410]ENV: EMBPERL_COOKIE_PATH=/ [6410]ENV: PATH=/sbin:/usr/sbin:/bin:/usr/bin [6410]ENV: MOD_PERL_API_VERSION=2 [6410]ENV: EMBPERL_SESSION_MODE=1
